If we're talking about Zodiarts look no further than Natsuji Kijima A.K.A the Cancer Zodiarts. He is basically the Zodiarts equivalent of Gentaro; wherever Kijima may be he is always telling some rakugo joke or just insulting his opponent in some hilarious way.
In Wizards of Waverly Place, Justin Russo actually uses a spell entitled "Ham it Up", which produces a literal large ham. When he, and later Alex, take a bite of the ham it immediately ascends them to large ham status.
The 1960s Batman. There was no point in even auditioning for a role, no matter how small, if you weren't ham through and through. Even the nameless mooks were Large Hams.
Cesar Romero's Joker was way over the top, rivaling Nicholson's.
Sebastian: "Your only destiny is to be the nail that gets hammered down. Bang, bang, bang!"
Centauri seem generally prone to overacting, but there's a reason Londo Mollari became Emperor, and it's not the Shadow/Rifa conspiracy.
Dr. Franklin, the head of medicine on Babylon 5, was played by Richard Biggs, who had an earlier career on television soap operas. In one "memorable" episode ("Walkabout"), Franklin is stabbed in the stomach and winds up having an imaginary conversation with himself, where the fake Dr. Franklin mocks and yells at the real Dr. Franklin. Meaning the scene essentially becomes a competition between two Richard Biggs, each trying harder than the other to overact as much as humanly possible.
Bruce Boxleitner, aka John Sheridan, could drift into this, although he also demonstrated his subtlety on any number of occasions, notably in his scenes with Delenn. Choice ham quote:
Shatner is only one of a smorgasbord of Hams on Boston Legal. 99% of the lawyers at Crane, Poole and Schmidt have a Master's in Chewing the Scenery (except for Brad), along with several of the judges ("It's shocking!, "Jibber Jabber!"), and most of the clients (remember Shirley's Stalker with a Crush?).
John Lithgow in nearly everything he's done since the 90s, including his role in 3rd Rock from the Sun as Dick Solomon:
Jimmy James, who was actually part of the regular cast.
Bill McNeil is the bigger ham on the show. Nobody else in television has actual lines like "BEGONE!!!"
In Stargate SG-1, virtually all of the Goa'uld System Lords were bonded to this trope at a subatomic level. Apophis, Anubis and Ba'al are probably the three standouts, though Chronos, Sokar and Yu are right up there. The real fun came from mixing character tropes: Anubis was a Large Ham, while Ba'al was an Affably EvilLarge HammingMagnificent Bastard, and ended up becoming one of the most popular characters in the series. Guest Star hams were probably led by Dom De Luise, who starred in the episode "Urgo" where he was amazingly annoying to everyone, including hamming it up to the extreme. Their enemies The Jaffa are often hammy as well, particularly Bra'tac. It probably comes from hanging around System Lords. All this hamminess might be unbearable if it weren't for the fact that Jack O'Neill is constantly making fun of this tendency.
It's not just the System Lords — pretty much all Goa'uld ever are Large Hams (well, except for the Tok'ra). It crops up as far back as episode two with the Goa'uld that infests Kowalsky: it's constantly yelling stuff like "HRRRRNGH RELEASE ME NOW!!!!". And that one was still in its larval state, so Goa'uld are basically Large Hamsfrom birth.
The Always Chaotic Evil Wraith from Stargate Atlantis are also like this, so much so that most of their dialogue in the first few seasons consisted mostly of variations of "I AM YOUR DEATH!" or "WE SHALL FEED!". This goes to such an extent that when, later in the series, a notably non-hammy Wraith (affectionately named Todd by Sheppard) becomes a recurring character, his straight, cynical delivery becomes hysterical.
Todd did have a few hammy moments, most notably in the episode Vegas:
"I know your destiny...JOOOOOOHN SHEPAAAAAARRD!!!"
Parodied by The Young Ones, in which a guest star Barry Stanton's particularly blustery appearance as the Postman in the Series 2 episode "Nasty" earns supposed "applause" from the Laugh Track while the real studio audience is still laughing. After exiting at the end of his scene, he can be heard recounting theatrical anecdotes in a loud voice from the wings until Vyvyan tells him to shut up.
Tobias from Arrested Development. And Barry Zuckercorn. And Lucille Austero. And Carl Weathers, and Wayne Jarvis, and Maggie Lizer... in fact, at least half the Recurrers. Still, only Barry (played by The Fonz himself) can out-ham Tobias.
Richard Hatch as Tom Zarek. He is usually fairly quiet compared to some of the ham on offer on this page, but prone to dramatic statements and poetic descriptions that stand in stark contrast to every other character, giving the impression he feels momentous times require momentous performances.
"Zeus has returned to Olympus"
Then there is the hard-boiled and harder-assed leader of the fleet, Adama.
And his often times drunken XO, Colonel Saul Tigh. Especially when he started to lose it near the end of season three.
Shawn Spencer from Psych - who is without a doubt the biggest pseudo psychic ham in all of network television. The show plays with the trope, as Shawn mainly hams it up when doing the psychic schtick, and it's deliberate.
Oh, he can ham it up pretty good without having one of his "experiences", particularly when dealing with Gus or his father.
Dad, please tell me you are wearing that shirt so someone can see you from SPACE!
Jonathan Harris as Doctor Zachary Smith. "Never fear, Smith is here!" "Oh, the pain, the pain." In fact, one of the complaints about The Movie was that Gary Oldman's Dr. Smith wasn't hammy enough.
Doug Walker's portrayal of the same character (though it's inspired by Oldman's version) is not only goofy and over the top, but terrifying beyond imagining. Unless you're somehow used to Noel Fielding playing this sort of character on The Mighty Boosh.
John Shea as Lex Luthor was all crazy-eyes, all the time. Not adverse to alternating slimy and seductive shtick with voluble intense outbursts of villainous venom.
Lane Davies playing Tempus, who is a time traveller from the future where Superman's secret identity is well known, indicating Superman revealed it at some point. Tempus is mocking Lois for being "galactically stupid" in not noticing that Clark Kent looks amazingly like Superman wearing glasses. (Tempus puts on a pair of glasses, "Look, I'm Clark Kent!". He then takes off the glasses, "Now I'm Superman!". Repeat several times in a sarcastic mocking tone.) Total ham.
The endlessly unexpected SPANISH INQUISITION!! from Monty Python's Flying Circus... but only when they can get their lines straight. Really, no matter what the character(s), the Pythons had plenty of opportunities to ham it up over the years. And the whole concept of the Large Ham is poked fun at in an Episode 25 sketch in which excessively melodramatic actors are committed to the Royal Hospital for Over-acting (their SHOUTING TENDENCIES in particular are addressed). There's a whole unit given over to performers who've gone too far in playing Richard III.
BRIAN BLESSED in everything he's ever been in. He's a trope unto himself.
As the friendly Greek handyman Spiro in My Family and other Animals (the 1987 original version, not the 2005 remake), from the books by British writer and naturalist Gerald Durrell about his memories of his childhood on Corfu during the 1930s.
The guy even played Saint Peter like this. Seriously.
Law & Order: Criminal Intent's Detective Goren, played by Vincent D'Onofrio, has been getting increasingly hammy over the years, though it is debatable whether this is a case of overacting or caused by the further development of the character's own psychological problems due to the stress of his work and family (and he was probably a few fries short of a Happy Meal to begin with).
Miss Piggy is a Large Ham in more ways than one, and an excellent female example.
Link Hogthrob also deserves the epithet, although he was (as Captain of the Swine Trek) a pastiche of Shatner himself, so it's expected.
While he's not a pig, Animal would also qualify. The Bob Hope episode would be the standout here, in which his reaction to Kermit telling him to get a hobby is to run around shouting "HOB-BY! HOB-BY! HOB-BY!", then take up alligator wrestling.
Josh is like this for the 1st and 2nd seasons, including him repeating words for emphasis. "EMPHASIS!"
One episode with Josh's rival Mindy had her exit grandly shouting about her cockapoo and her exact clone of that cockapoo.
SCTV satirized this with such characters as Lola Heatherton and Count Floyd. Two very noticeable examples being Johnny LaRue and Bobby Bitman. The latter being a parody of Vegas style comedians, every bit of him is hammy including his catchphrase "HOW ARE YA?".
Frasier Crane any time something riles him up. It began in Cheers with his classic "YOU WILL *RUE* THE DAY YOU DID THAT!", which became a semi-catchphrase.
"IN YOUR FIREY THRONE PRESIDING OVER THE DAMNED!"
And then in Frasier, his brother Niles is almost as large a ham as him, albeit with a somewhat different style. And the two see each other almost every day and have loads of Sibling Rivalry, meaning buckets and buckets of delicious Ham-to-Ham Combat.
In "The Show Must Go Off" episode, Frasier & Niles, when they were piglets, were awed & inspired by Jackson Headley (played by Derek Jacobi) acting in Shakespeare, e.g. "King Lear." But after Frasier re-discovers him & he & Niles watch him do the last scene of, um, Hamlet, they're aghast, & more so after re-viewing a videotape of that "King Lear" performance.
Jackson Headley: "Oooohhhh! I diiie, Horatio! GASP! The potent poison quite o'er-crows my spirit: GASP! I cannot live to hear the news from England; But I do prophe-sigh...the election lights...on Fortinbras: GASP! He has...my dying voice. The rest...is......(whispered) silence. GASP!"
John Larroquette tends to be all over this trope, as shown in any episode of Night Court, his guest spot in Chuck, and a memorable guest spot in The West Wing.
Lionel Tribbey: "I will KILL people today, Leo! I will KILL people with this cricket bat, which was given to me by Her Royal Majesty Elizabeth Windsor, and then I will kill them again WITH MY OWN HANDS!"
Speaking of The West Wing, Lord John Marbury is also incredibly hammy:
The Sarah Connor Chronicles has Doctor Silberman's return in "The Demon Hand" as a psychotic, deranged man living in the mountains, who starts off as a fairly calm and collected person who steadily begins chowing down on larger and larger servings of ham. By the end of the episode, he's thrashing about in an insane asylum, screaming "THEY'RE EVERYWHERE!"
"You think you can just do that to me? You THINK I'd let you get AWAY WITH IT?HA HA!THINK AGAIN!"
For context: While saying this he is pointing a gun at Buffy. The line is designed to show that he's coming unhinged, and took the whole "evil nemesis" thing vastly more seriously than the other two members of the trio.
Wesley: "I love you so much I almost forgot to brood!"
Really, from the second season finale of Angel onward, Charisma Carpenter seemed to be contractually obligated to gnaw on the scenery whenever she was on camera.
In Buffy's Musical Episode, "Once More With Feeling", most of the cast release their inner hams during their musical numbers (except Alyson Hannigan, who spends most of the episode looking profoundly uncomfortable, as she was apparently less than enthused by the musical idea - which would explain why she's the only one who doesn't get a solo number or a duet). James Marsters (playing Spike) in particular appears to be having way too much fun.
Fridge Brilliance, of course; Alyson Hannigan's character was established as having chronic stage fright and being uncomfortable with singing as early as the first season. On the other hand: When Alyson mimed to the "mustard song" between takes, she definitely hammed Up to Eleven.
Balthazar, a huge demon who yelled and splashed around in a little pool of water, was one of the hammiest characters in the entire series..
One of the most memorable hammy villains was Devastation from SPD. This guy's entrance was punctuated by fireworks, and he said his own name upon appearing on the scene. After trouncing the Rangers, he actually told them to "marinate...IN FEAR!" As opposed to Devastation himself, who seemed to have been marinated in animal fat and then lightly basted before being served up as Christmas dinner. He sounds just like "Macho Man" Randy Savage.
While not necessarily the most iconic ham, a villain whose catchphrase is "Viva La Diva, baby!" has to be the Ur-example in this category. Some of Divatox's more memorable moments were "ARISE...AND MEET YOUR BRIDE!" and the somewhat famous "I LOVE it when a plan comes together!"
Tenaya 7 of Power Rangers RPM is frequently pausing in the middle of fights to make speeches, which she never gets to finish.
Rita Repulsa's iconic screeching voice has yet to be topped. "I'VE GOT SUCH A HEADACHE!"
Zordon himself was a large ham in the tradition of Optimus Prime, with very little actual drama to it, but several metric tons of gravitas per syllable.
Antonio the Gold Samurai Ranger from Samurai impressively out-hams the entire franchise to date. Ironically enough, for all the ham he's got, his theme is seafood. Take his debut where he shows off his Ranger form for the first time:
Antonio: Now this... is a big moment. Man, this is gonna be so golden! Now let's do this! Samurai Morpher! Gold power! [Transformation Sequence] Gold is good to go! [Beat] That's it? No "Thanks for helping"? Or a little "What? What?" Alright, I get it. You need a minute. What can I say? When I make an entrance, it's go BIG, or go home! Am I right?
And when you say Power Rangers, realize that the Super Sentai counterpart can be hammy when it requires to do so. I mean, look at Samurai Sentai Shinkenger's Ikenami Ryuunosuke (A Kabuki actor known to yell "TONOOOOOOO!!!") and Umemori Genta (over the top sushi seller, the counterpart of Antonio above). Together they're known as the "Ham Sandwich" after all.
Not even just Gai, their entire arsenal is incredibly hammy thanks to Tomokazu Seki (Example "FIIIIIIIINAL WAAAAAAAAAAAAAAAAAAAVE")
Nobuo Akagi from Hikonin Sentai Akibaranger is pretty hammy in his own right whether it involves conjuring up one his favorite Sentai heroes or imagining any one of the female characters in Sentai cosplay.
One word: Flabber (of Beetleborgs). He's one hammy flabberific phasm. It helps that his mannerisms are based on Jim Carrey as Ace Ventura and that he's also a cross between Robin William's Genie and Jim Carrey as The Mask.
Fangula from the same series. He was based on Dracula though, and that makes it a prerequisite.
Zor-El from Smallville. "THE BLOOD OF THE HOUSE OF EL RUNS THROUGH YOU!"
And when Michael Shanks makes guest spots as Carter Hall/Hawkman, scenery will shake and be chewed to pieces.
Large Ham seems to be a requirement to play a Smallville villain. From Season 1, John Glover is beautifully over the top as TheMagnificent Bastard, Lionel Luthor and Michael Rosenbaum's Lex Luthor gets hammier with each season that passes. Cassidy Freeman is a female example as their successor, Dark Action Girl Tess Mercer. And then there's Callum Blue as Major Zod. "Unlike you I will lead from a throne, not from the shadows! Everyone on earth, including the woman you love, will Kneel Before Zod!" As of Season 10, Mackenzie Gray has been hammishly Ax-Crazy as Lex's aging, dying clone, and Ted Whittal as Rick Flag? Whoo boy. He recites the Star Spangled Banner as he fires a missile at General Lane. He's not as loud as the other examples, but the sheer intensity Whittal brings to the character puts him here.
Wash sometimes count, especially when playing with his dinosaurs.
Alan Tudyk takes his hamminess to scary levels in Dollhouse.
Leo McKern, everyone's favorite second in command on The Prisoner. "DEGRRRREEEE ABSOOOOLUUUUTE!" McKern himself has had a hamtastic career-spanning performance as Deadpan SnarkerRumpole of the Bailey, especially when he's in the throes of his particularly sarcastic brand of advocacy.
In-character example: Sophie Deveraux from Leverage is an incredibly skilled and versatile con artist... when she's on a job. Unfortunately, all she really wants to do is act.
Keith Olbermann of Countdown with Keith Olbermann enjoys eating a large ham sandwich before delivering the news. He double doses before his Special Comments.
The IT Crowd has Matt Berry (who manages to ham up adverts) as Douglas Reynholm, and his ffffaaaather Denholm Reynholm played by Chris Morris, both of whom did some great Ham and Cheese.
Matt Berry's stint in The Mighty Boosh playing Dixon Bainbridge was a classic slice of Ham. Also, any character ever played by Rich Fulcher, from series regular Bob Fossil, to Howard's blind friend Lester Corncrake, to pretty much any one-off character - he steals every scene he's in. Bainbridge and Fossil's spontaneous rendition of "Total Eclipse of The Heart" was a high-point (and a Crowning Moment of Funny).
Every actor in the 1970s sci-fi series Space: 1999 is either completely wooden (Barbara Bain is lucky Emmys can't be rescinded by ATAS), or producing metric tons of ham. Sometimes in going from one to the other in the space of a single line. "Death's Other Dominion" and "The Metamorph" featured BRIAN BLESSED (in different roles).
The laziest and hammiest person in LazyTown is without a doubt Robbie Rotten. Portrayed in an over-the-top style similar to Jim Carrey's portrayal of the title character in How The Grinch Stole Christmas. He'll keep on hamming........''FOREVER!!'.
The ULTIMATE ham of 24 is Jack Bauer... the show wouldn't be a tenth as good if Kiefer Sutherland played the role low-key.
"Who is the ham man in Visalia!?!?"
"Where's the ham bomb?!?!".
In the 7th season John Voight played Jonas Hodges, an executive at the Private Military Corporation Starkwood, part of the Cabal that has been present since Season 5. He was also one of the hammiest villains with bizarre dialog like:
"Stress is the fertilizer of creativity. Now, let's play some darts."
"They're six year olds, Greg. And they need to eat their carrots."
Although Dennis Haysbert's performance was very subtle, President David Palmer was certainly not above snacking on scenery.
"That is an obscene suggestion!"
Ham must be a Palmer family treat. Sherry, Wayne, and Sandra Palmer all bust out several plates of ham when they deem it necessary.
Now compare the Palmers to total nut-case and Manipulative Bastard Charles Logan. Enough ham for days.
Jenna Maroney on 30 Rock does this in-universe both on and off camera. She's apparently even petitioned the people who run the Tony Awards to add a category for "acting theatrically in real life." Tracy Jordan gets his moments, as well.
Also, while Alec Baldwin is very capable of subtle acting, every now and then he breaks out a big old Irish ham.
In Farscape, out of all the hammy villains encountered, Maldis is by far the hammiest:
"YOU KNOW WHAT I THINK, JOHN?! YOU CAN TALK 'TILL YOUR TONGUE FALLS OUT! HE'S GONNA KILL YOU REGARDLESS! AAAAAAAARRRRRGHH!"
Queen Sophie-Anne Leclerq from True Blood (as played by Evan Rachel Wood), though she is rapidly being edged out by Russell Edgington.
Harland Williams. A good example of his hamming it up, interestingly, come from the commercial bumpers that they had him appear in for Kids WB (view some of them here; needless to say, someone at Warner Bros. soon realized we didn't need him to tell us that The Sylvester And Tweety Mysteries was back from the commercials in a Dracula voice.
I, Claudius. It stars BRIAN BLESSEDandJohn Hurt! Virtually everyone gets moments of large ham. Livia, Julia, Augustus, Caligula, the Sibyl prophetess from the beginning, etcetera.
"IS THERE ANYONE IN ROME WHO HAS NOT SLEPT WITH MY DAUGHTER?!??!"
Harry Hamlin's Uncle Marty in Harper's Island. Who goes to the abattoir at the end of the first episode.
MythBusters: Adam in particular, but anyone who isn't Jamie qualifies to some degree.
Ian McNiece plays a massive slab of Classical Ham as the really epic Forum newsreader in Rome, complete with Milking the Giant Cow posing.
Mc Niece is one of the hammiest characters out there, particularly in his roles as Baron Vladimir Harkonnen in Dune and Children of Dune, Wagonmaster General Runciman in Sharpe's Battle and as Winston Churchill in Doctor Who.
Dr. Simon Finch-Royce: "Ok; Sam, Diane, you two are perfect together. I'm sorry I made a mistake before but you are the most perfectly matched couple ever. But, why am I telling this to you? Let's share it with the rest of the world. (yells out a window) Hear this, world. The rest of you can stop getting married. It's been done to perfection! Envy them, sofa, envy them, chair, for you shall never be as cozy as they for their union shall be an epoch-shattering success and I STAKE MY LIFE ON IT. Wait a moment! Let me get this on record (talks into his tape recorder) "I, Dr. Simon Finch-Royce, being of sound mind and body declare that Sam and Diane shall be happy together throughout all eternity and if I am wrong I promise I will take my own life in the most disgusting manner possible!" Here, take the tape, NO, take the whole machine! It's my wedding gift to you. The most perfect couple since the DAWN of TIME!"
Dylan Moran in Black Books. Bill Bailey has his moments as well.
Dylan Moran's stand up (especially once you realize he's playing a character) is also full of these moments.
"I cannot convey to you in words exactly how much I DON'T CARE!!! I didn't even know we had windows until you pointed them out to me!"
An episode of Amazing Stories is about a pair of teenagers who decide to kill their English teacher, who is played by our dear Mr. Lloyd. If his over-the-top performance as Mr. Beanes (no relation) wasn't enough for you, the kids realize their mistake and try to resurrect him but accidentally tear the needed photo of him in half at the neck. So yes, he spends half the episode carrying his head as he chases them around, all the while threatening them with school work and flinging family-friendly head-related puns as fast as he can. Which, this being Christopher Lloyd, means he's chewing the scenery like it was made of Laffy Taffy. The episode ends with a fantastically narmyreveal where zom-Beanes responds to the question "are you okay" with "Well... actually... I have a bit of a... SORE THROAT! AHAHAHAHAHAHA!!!" while he takes off his scarf to show the line of stitches around his throat. It's epic.
As befitting a town where pigs play a vital role in the local ecosystem, Deadwood is absolutely packed to the gills with Large Hams:
Calamity Jane: "Cocksuckers!"
E.B. Farnum: "No deceit. Too prolonged. No errand too demeaning. Get outta here! No rebuke too vile. Al Swearengen's a cue and Farnum merely his billiard ball. Shit! Quagmire of piss and bullshit!"
Cy Tolliver: "Don't fuck with the fuckin' deity, Leon! You've got to come to him wholehearted, even when you're asking for partial relief. Oh, Lord! Let Leon cut down, Lord, on the motherfuckin' dujie."
Jack Langrishe (both in and out of character): "I am BAREly speakin' to YOU!"
Mr. Wu: "WU! AMERICA!"
Days of Our Lives - Soap operas in general have their share, but one Days cast member stands out above all others - Louise Sorel, whose portrayal of the scheming, stark-raving-mad Vivian is so far over the top it's halfway down the other side. And studded with cloves. And pineapple.
I will go to the animal shelter and get you a kitty cat. I will let you fall in love with that kitty cat. And then, on some dark, cold night I will steal away into your home... AND PUNCH YOU IN THE FACE.
Half the characters on The League of Gentlemen qualify, though no amount of make-up can mask the demented glee on Reece Shearsmith's face when playing Papa Lazarou. Special mention goes to Tubbs and Edward from the same series.
Everyone on Gilligan's Island was a Large Ham - even by the standards of that hammiest of decades, The Sixties. By their standards, Jim Backus, as Thurston Howell III, went so far above and beyond, it's hard not to believe that he's actually a pig in disguise.
Jeremy Brett's brilliant performance as Sherlock Holmes was rife with ham, his version of Holmes having No Indoor Voice and tendency towards rambling and manic-depressiveness, much like his original book counterpart.
Alex Kingston as Mrs Bennett in Lost in Austen. Kingston is more than capable of giving a subtle, nuanced performance (and has even done so on Show Of Ham Doctor Who most of the time) - but she chucked it all out the window and went to town as Mrs Bennett. Although to be fair, anyone who doesn't play Mrs Bennett as an over-the-top piece of smoked, delicious ham is doing it wrong.
To be fair, she has her hammy moments on Doctor Who as well, such as her opening scene from "The Time of Angels"note Although let it be noted that it is debatable whether it is Kingston who is being the Ham, or River.:
River: "You might want to find something to hang onto."
While a lot of Immortals on Highlander probably qualify, Kronos really stands out.
Slan was a good example of this. Adrian Paul wandered into it once, during Darius's death scene.
Duncan: DAAARRRRIIUUUSSSS! DARIUS! (check out the onscreen expression and it'll be clear).
X-Play's Johnny X-Treme, a parody of the "extreme" trend in the mid-00's who spouted absurd catch phrases, broke beer bottles on his crotch, and made a game with a boss battle that involves a T-Rex with a hammerhead shark for a head (the entire shark) in front of the White House.
Johnny X-Treme: IT'LL PUNCH YOUR BALLS OFF!'
The Twilight Zone episode "The Little People" with Joe Maross as power-mad spaceman Peter Craig shouting "I'M THE GOD!, I'M THE GOD!" as he gleefully stamps on the little aliens' city. A line that was parodied by Dr. Forrester in the MST3K Movie.
Will Friedle as Eric Matthews in the later seasons of Boy Meets World. He started out fairly subdued, but as Eric got crazier and Friedle developed better comic timing he added more and more ham to his performance until he became a full on large ham by about season six.
Jacks Teller from Sons of Anarchy, whenever he is angry with someone, takes this to ridiculous levels. It's particularly noticeable because he loses his temper very often. The other characters, especially Clay, usually try to resolve things peacefully.
Lenny Henry's titular character in Chef definitely qualifies.
Chef Gareth Blackstock: Everton, please remove the maggots, rat carcasses, and corpses of shocked health inspectors and make the place fit for the preparation of sodding food!
Chef Gareth Blackstock: Somebody bring me a knife, very long and razor sharp. I need to castrate the person who made this sauce and I don't want to cause any unnecessary suffering. I'm not a vindictive man, I'm not out to cause pain, but with this man's DNA in the gene pool, humanity is doomed.
Pick a panelist from an episode of Around The Horn. Any panelist. Any episode. Odds are they will lapse into large ham territory at some point. Host Tony Reali can get pretty hammy himself.
The portrayal of Constantine the Great in The BBC documentary Ancient Rome: The Rise and Fall of an Empire with his fondness of Chewing the Scenery is definitely this trope.
Virtually every guest star on The Wild Wild West was a big slab of bacon, but the Largest Ham of all was Michael Dunn, who stood less than 4 feet tall.
He was nowhere near as OTT as Patsy Kelly ("The Night of the Big Blast" and "The Night of the Bogus Bandits"), Karen Sharpe in "The Night of the Ready-Made Corpse" - "TERRIBLE! TERRIBLE!"note not a description of her acting in this episode, one of her actual lines of dialogue in it (this episode was directed by Irving J. Moore, who liked his actors to go into orbit - tellingly, Sharpe's performance in "The Night of the Flaming Ghost" is ham-free) - or John Harding as Thaddeus Toombs in "The Night of the Winged Terror," a man so hammy he had to have two episodes to fit all the porkiness in! (Coincidentally, this was the show's only two-parter.)
But if you're looking for Ham in large portions, Victor Buono (as Count Manzeppi) is your man (see above).
Baron Ambrosia, of The Culinary Adventures of Baron Ambrosia, is but one Large Ham among many (and since it's on The Cooking Channel, it could potentially be a literalWorld of Ham).
Game show hosts have always been known to be a bit hammy, but the 1970s revival of Match Game turns it Up to Eleven with Gene Rayburn, Brett Somers, Richard Dawson and Charles Nelson Reilly milking it for all they've got—no brow too low, dignity be damned. If it got a laugh, then roll with the punches.
When Richard Karn was the host of Family Feud, he would often display this in his hosting style. Most notably in shouting "I'M DOUBLING/TRIPLING THE POINTS!!!" before the double and triple rounds, and "TWENTY THOUSAND DOLLARS!" in the Fast Money Bonus Round.
Steve Harvey, who took over in 2011, likes to shout at contestants and mug the camera when a particularly off-the-wall answer is given.
Rowan and Martin's Laugh-In:Many castmembers (Along with several guest stars) have their moments, but no one chews the scenary more than Jo Anne Worley.
C'mon Midffîld has Mr Arthur Picton, a very short-tempered football captain who happens to have the most incompetent football committee in Wales. When your referee is an absolute idiot and screws up the game from the other side of the pitch, you need a giant voice to set him straight - "''WALI, Y BLINCING TWMFFAT!".
Ian Wright was by far the hammiest of the hosts in The Travel Channel's Globe Trekker.
Wright: [upon meeting a bunch of Dir En Grey cosplayers in Shinjuku] "ARE YOU GUYS MONSTERS?!"
