'''William Henry "Bill" Cosby''' (born July 12, 1937) is famous for his versatility over his long career; he broke barriers for his fellow African-American entertainers.

Born and raised in the UsefulNotes/{{Philadelphia}} projects, Cosby attended Temple University as a phys.ed major but eventually dropped out to become a standup comedian in the mid-1960s. He was an immediate success, in part because his material — in sharp contrast to most of the black comedians of the day — was largely apolitical, based instead around Cosby's friends and foibles growing up and the perils of raising his own family of five. Defending this choice, Cosby once noted: "A white person listens to my act and he laughs and he thinks, 'Yeah, that's the way I see it, too.' Okay. He's white. I'm Negro. And we both see things the same way. That must mean that we are alike. Right? So I figure this way I'm doing as much for good race relations as the next guy."

Success in the clubs led to an impressive string of hit comedy and music albums, including the now-classic "To Russell, My Brother, Whom I Slept With" and the, er, genesis of the similarly beloved "Noah" routine ("'''It's ''The Lord'', Noah.'''" [[CassandraTruth "Riiiiiggght!"]]). ''AudioPlay/IStartedOutAsAChild (1964)'' was the first album by Cosby to feature stories about his childhood, which would eventually inspire the ''Fat Albert'' cartoon series in the 1970s. These stand-up albums were followed in 1965 by a groundbreaking role alongside Robert Culp in the SpyFiction {{dramedy}} ''Series/ISpy''. It was the first time a black actor had ever starred in a television drama, and it earned Cosby the first Emmys (three total) a black actor had ever received.

Naturally, in 1969, the next step was ''Series/TheBillCosbyShow'' — no, not that one, the one that featured Cosby as Chet Kincaid, high school gym teacher. No, really, it ran two whole seasons. He even sang the theme song.

The 1970s saw the re-emergence of William H. Cosby Jr., who had gone back to school to earn his doctorate in education. ''WesternAnimation/FatAlbertAndTheCosbyKids'', a hit (12-season!) animated take on the old routines featuring his friends in the projects, and ''[=PicturePages=]'', short interactive educational skits as part of ''Series/CaptainKangaroo'', were the most prominent initial results of this new interest. Also included were memorable guest-starring stints on both ''Series/SesameStreet'' and ''Series/TheElectricCompany''.

At this undisputed high point, he was even starring in hit films with Creator/SidneyPoitier: ''Uptown Saturday Night'' and the sequel ''Let's Do It Again'', made as a rebuttal to the violent, one-dimensional {{Blaxploitation}} films then popular. Somehow, though, while that genre has emerged beloved and even homaged, Cosby's own film career... has not. By the time vanity project ''Film/LeonardPart6'' debuted in 1987, Cosby was reduced to instructing talk show audiences ''not'' to see it, by way of salvaging his big-screen reputation.

Much better received was his 20-odd-year side career as pitchman for Jell-O pudding. Cosby was a fitting spokesman for the product, having mentioned it by name in multiple stand-up routines, perhaps most notably smearing it on the floor as a child to use as booby trap to protect himself against monsters. The standard spot featured Cosby mugging shamelessly while surrounded by cute moppets and — of course — lots and lots of chocolate pudding. Not at all surprisingly, they were instrumental in switching his image from young, hip urban dude to goofy sweater-wearing curmudgeon.

This is how the current generation (or two) knows him best: as Cliff Huxtable in the classic SitCom ''Series/TheCosbyShow'', which lasted from 1984 to 1992 on Creator/{{NBC}} and was again based around his old routines, this time those featuring his own family. At loose ends (largely due to by-now hopeless typecasting as that same curmudgeon) once it left the air, he took on the TV equivalent of odd jobs, hosting ''KidsSayTheDarndestThings'' and the 1992 revival of ''Series/YouBetYourLife''. He also dabbled in detective drama (the ''Bill Cosby Mysteries'', natch) for the ''ABC Mystery Movie'' revival, and created the animated Creator/{{Nickelodeon}} series ''WesternAnimation/LittleBill'' and ''WesternAnimation/{{Fatherhood}}''.

His last fling at prime-time television was the 1996–2000 sitcom... wait for it... ''Cosby'', in which he played a lovable ''elderly'' curmudgeon in a scenario loosely based on the Britcom ''Series/OneFootInTheGrave''. However, the episode most remembered by fans was a fourth-wall ''destroying'' episode in which Cosby's character dreamt that he was Alexander Scott from ''I Spy'' (complete with guest appearance by Robert Culp), and Cosby's wife dreamt that she was a character in ''The Cosby Show''.

At last notice, he is participating in the development of a modernized revival of ''Fat Albert and the Cosby Kids''.

Cosby's diverse range of material has netted him four Emmy Awards and nine Grammy Awards for his many albums... and a Razzie, for ''Leonard Part 6''. He has written best-selling books, hosted comedy festivals, and — most recently — campaigned publicly against what he perceives as a lack of ambition and drive within the African-American community. This last role has earned him considerable controversy, mitigated somewhat by sympathy after the murder of his only son, Ennis, in 1997.

In November 2013, Cosby did his first stand-up special in nearly 30 years, ''Far From Finished'', which aired on Creator/ComedyCentral. To date, this has been his last hurrah. Numerous accusations of sexual assault that have subsequently come against Cosby have permanently damaged his public image and have more or less ended his career.

Not to be confused with actor [[Film/NightAtTheMuseum Bill Cobbs]]
!!Tropes present in Cosby's work:
* AluminumChristmasTrees: A lot of people thought the "Chicken Heart Story" was a fakey ''Radio/LightsOut'' episode that Cosby made up for the routine. There was indeed an actual episode of ''Lights Out'' called "The Chicken Heart" and it actually was [[https://www.youtube.com/watch?v=G_OD_jUnYNM surprisingly rather creepy.]] Be sure to have your Jell-O prepared!
* {{Angrish}}:
** "Did you ever make your mother so mad that she forgot your name? 'Come here, [[RapidFireNameGuessing Roy—uh Ralph—Roquefort— Rutabaga]]—what is your name, boy? And don't lie to me, 'cause you live here and I'll find out who you are! Take a stick and knock your brains out!'"
** Later in the same skit: "I used to think my father was an idiot because the man could not complete a full sentence... Now I understand ... had it've been a grown person, you'd have cursed: 'What the [[ClusterFBomb foul filth foul foul filth filth filth foul foul! And you're filth and foul!]]' But you talk to your child, [[CurseCutShort you censor yourself]], and you say, 'What the... Get your... I'll bust... Get outta my face!'"
* AnswersToTheNameOfGod: Inverted:
-->It was because of my father that, from the ages of 7 to 15, I thought that my name was Jesus Christ, and my brother, Russell, thought that his name was Dammit. "Dammit, will you stop all that noise?" And, "Jesus Christ, sit down!" One day, I'm out playing in the rain, and my father yelled, "Dammit, will you get back in here!" I said, "Dad, I'm Jesus Christ!"
* BannedEpisode: Thanks to the rape allegations, ''TheCosbyShow'' now gets this treatment on cable networks, including [=TVLand=]. It may become permanent depending on how Cosby's situation plays out. It was not immediately known whether the current [=TVLand=] ban also includes local stations that air the legendary situation comedy, or if other programs starring Cosby are or will be included. However, at least on the Viacom-owned [=TVLand=] (and its related networks), mere references to ''The Cosby Show'' have been removed from the website altogether[[note]] (often, even shows that formerly aired on the network and not currently accessible from the main page can be accessed if one knows how to search the site)[[/note]], and while the complete series is available on DVD, it may be a very long time - possibly never – before the 1984-1992 sitcom is aired on TV again.
* BigShutUp:
** During "Natural Childbirth", as his wife gets hit with contractions and she demands morphine:
---> I said, "But dear!" ''[imitates Lamaze breathing]'' She said, "YOU SHUT UP!!! ''YOU'' DID THIS TO ME!"
** He also says this when he talks about his mother's [[HypocriticalHumor hypocritical]] parenting skills:
---> When a mother asks you a question and you try and answer, she tells you to shut up! "Day and night, night and day, work my fingers to the bone, and for what?" "I don't--" "[[PunctuatedForEmphasis Shut! UP!]] When I ask you a question, you keep your trap shut! Think I'm talking just so I can hear myself ''talk?!'' '''''[[MortonsFork ANSWER ME]]!!!'''''"
* BlazingInfernoHellfireSauce: The "Chinese Mustard" routine about the time when he took a girl to a Chinese restaurant as a teenager. Being broke, he attempted to get as much as he could for his money and dunked his entire egg roll in the mustard. His description of his reaction on biting into it is priceless.
* BrickJoke: "Natural Childbirth":
--> "Creator/CarolBurnett described what labor pains feel like. She said, 'Take your bottom lip and pull it over your head.'"
--> "Then my wife stood up. In the stirrups. Grabbed my bottom lip. And said, [[PunctuatedForEmphasis 'I! WANT! MORPHINE!!!]]'"
* BringMyBrownPants: "Grandparents":
--> ''And mothers are always more interested in the condition of your underwear than your body if you're ever in an accident. And they tell you that; "I hope for my sake if you're ever in an accident, you have on clean underwear." Well, I thought that's what an accident was! Look; you're driving a truck. Here comes another truck, gonna hit you. Now, whether you hit the truck or not, you're going to have soiled underwear. Because first you say it, then you do it! Now comes your mother to the hospital: "Did he have on clean underwear?" "Yes, we found it in the glove compartment."''
* ContractualPurity: In ''Far From Finished'', he talks about a few of the reactions he got when telling people he was getting a special on Comedy Central. One grown man burst into tears and shouted "Mr. Cosby's gonna swear!", apparently having his childhood destroyed by the mere thought of it. Another guy was also really hoping and expecting him to swear to a creepy level. He doesn't actually swear in the special, perhaps because of one or both of these reactions.
* CoolCar: Played simultaneously for [[PlayedForLaughs laughs]] ''and'' [[PlayedForDrama drama]] in the titular story of the album ''200 [=MPH=]'' which, for bonus points, is a true story about his brief ownership of a [[http://en.wikipedia.org/wiki/AC_Cobra#Super_Snake Shelby Cobra Super Snake CSX 3303]]. Among other things, he describes it as trying to kill him while he was idling it in his own driveway.[[note]]Its next owner, after Cosby returned it, ''did'' die from injuries caused by falling into the Pacific Ocean after losing control.[[/note]]
* DemonHead: His wife when he feeds his kids chocolate cake for breakfast.
--> "I've always heard about people having a 'conniption', but I'd never seen one. You don't wanna see 'em. My wife's face...''split''. The skin and hair split and came off of her face so that there was nothing except a skull. And orange light came out of her hair and it lit all around. And fire shot from her eye sockets and began to burn my stomach."
* EpicRocking: Yes, he actually played this trope ''straight'' with the ''Badfoot Brown'' pair of albums; the former contains one song per side: [[http://www.youtube.com/watch?v=h6hRvwaXzFo "Martin's Funeral"]] on the first and [[http://www.youtube.com/watch?v=KZmQE7nkvck "Hybish Shybish"]] on the second. Cosby wrote and played electric piano on these two songs.
* TheEponymousShow: A trademark, epitomised by ''Series/TheCosbyShow'', of course.
* ExplosiveBreeder: During his "Noah" routine, he had to repeatedly remind the rabbits "Only two, only two" when two of every animal were boarding the ark.
* FakeRabies: "Roland and the Rollercoaster" deals with his crazy friend Roland, who used to do things like keep soap chips in his mouth. When people think Roland's head has been turned around by the roller coaster (due to Roland wearing his clothes backwards), there is a throwaway line from someone seeing Roland: "And he's got the rabies!" It's a good Brick Joke as it usually takes the audience a few moments to remember the soap chips in the mouth (which was mentioned early on in a fairly long story).
* FirstGrayHair: In ''Time Flies'', he points out that he didn't mind the hair on his ''head'' turning gray, because he thought it made him look dignified. His ''pubic'' hair, on the other hand...
* {{Flanderization}}: The most popular media portrayal of Cosby (thanks to ''WesternAnimation/TheSimpsons'' and ''WesternAnimation/FamilyGuy'') is that of a [[{{Cloudcuckoolander}} gibbering, crazy old man.]]
* TheFourthWallWillNotProtectYou: The "Chicken Heart" story of the radio program ''Lights Out'' ends with the titular monster paying the audience a visit. "It's in your home state!" *bump-bump* *bump-bump* "It's outside of your door!" *bump-bump* *bump-bump* "And it's going to eat ''you'' up!" It scares Little Cos badly enough to both smear Jell-O all over the floor ''and'' set the sofa on fire.
* GargleBlaster: The "Fernet Branca" routine. After mistakenly ordering a revolting dish of barbecued sparrow in Italy and forcing himself to eat it, he develops a roaring case of indigestion. He takes a drink of Fernet Branca (a liqueur with an intensely bitter flavor) to settle his stomach, with the following results:
--> '''Cosby:''' The bird saw what was coming and started running...and ''I'' started running!
* {{Gasshole}}: ''Himself'' closes with a skit about how fathers are the only people in the house who are allowed to pass gas. He says that his father used to do it and blame it on invisible animals, which his brother Russell was dumb enough to go looking for. The last line of the special is him stating that his father's game was "pull my finger".
* GreyGoo: Mentioned in a retelling of the old radio serial ''Lights Out'' and its "Chicken Heart" episode. The routine is probably [[WeirdAlEffect far better known]] than the original audio drama.
* HilariouslyAbusiveChildhood: [[http://www.youtube.com/watch?v=Tt33zqib2qk At least according to his act]]. Dunno whether it actually was.
* HypocriticalHumor: "Dentists tell you not to pick your teeth with any sharp metal object. Then you sit in their chair, and the first thing they grab is an iron hook."
* IndecipherableLyrics: Much of Cosby's forays into music have consisted of him doing this, including the theme song to his own ''The Bill Cosby Show'' (credited to Cosby himself and Quincy Jones - Jones later recorded it as "Hicky-Burr").
* InflationNegation: Cosby has a stand-up routine in which he says that grandparents will give you money; all that you have to do is listen to a story about how much the money used to be worth. He quotes his grandfather saying that he once had 50 cents and bought "a house... and a car... and put 17 cents in the bank."
* InsaneTrollLogic: "Chocolate Cake for Breakfast," wherein, having been woken out of a sound sleep to go feed the kids breakfast, he gives his kids the chocolate cake they clamour for after rationalizing that it's ''healthy'' for them — because, after all, it has wheat and eggs and milk. And when his wife demands to know why they are eating it for breakfast, his kids pipe up, "''We'' asked for [[BlatantLies eggs and milk! AND DAD MADE US EAT THIS!!!]]" So his wife sends him to his room. [[{{Unishment}} Which is where he wanted to go in the first place.]]
-->"[Men] are the geniuses of the house because [[ObfuscatingStupidity only someone as smart as we could fake such stupidity. [...] We are dumb, but we are not so dumb. It takes great skill and work to keep from working]]."
* IronicEcho:
** In the second part of the "Noah" three-part routine:
---> '''Noah's neighbor:''' Listen, what's this thing for, anyway?\\
'''Noah:''' I can't tell you. Ha-ha-ha-ha-ha-ha-ha-ha!\\
'''Noah's neighbor:''' Well, I mean, can't you give me a little hint?\\
'''Noah:''' You want a hint?\\
'''Noah's neighbor:''' Yes, please.\\
'''Noah:''' How long can you tread water? Ha-ha-ha-ha-ha-ha-ha-ha!
** In the third part, when Noah's griping at {{God}} about all the hassle and ridicule he's gone through:
---> '''God:''' ''Noah?''\\
'''Noah:''' Yeah?!\\
'''God:''' '''''How long can you tread water?'''''
* IronicEchoCut: In "Driving in San Francisco", after stopping on a hill so steep that he's afraid he'll roll backward as soon as he lets go of the brakes:
--> '''Cosby:''' Well, I don't want to let [the guy behind me] know I can't drive, so I say "Come around, idiot, come around!" but he can't hear me because he's busy telling the guy behind ''him'', "Come around, idiot, come around!"
* {{Irony}}: Several times on the ''Revenge'' album:
** In the title track, Bill plans to hit Harold with a snowball, but Junior Barnes hits him with a slushball instead (prompting Bill to complain [[IronicEcho in much the same way Harold always does]]). Bill ends up saving a snowball in his freezer, but when he goes to use it against Junior Barnes in the middle of July, he discovers his mother had found it and thrown it away. (Undaunted, he spits on Junior Barnes instead.)
** In the second half of "Buck, Buck", Bill is taken in by a prank involving a statue of Frankenstein's monster. When he tries to help play the same prank on Fat Albert, it backfires on him: "I forgot I was behind him." Cue Fat Albert (described minutes earlier as weighing 2,000 pounds) trying to run away...and so terrified he doesn't even realise he's trampling Bill into the ground in the process.
** Then, they take Bill to the hospital and put him next to "a wino who was run over by two kids." In the previous track, "9th Street Bridge," Bill and Harold [[BrickJoke ran into a wino in the dark]], mistaking him for a monster and trampling him as they ran away.
** Also in his first album (''Bill Cosby Is a Very Funny Fellow...Right!''): His football coach's pep talk prompts them to "really wanna smash together"; they run out and the door is locked.
* JumpScare: "Well, listen, man. When the nurse leaves, I'll talk to you about that ice cream later... cause we're gonna eat a '''MESS''' of ice cream, Jack."
* KidsShouldntWatchHorrorFilms: His "Chicken Heart" routine. It culminates in him smearing Jell-O on the floor to trap the giant heart and setting the couch on fire, which his father slips on, breaking his arm.
** There's also the incident with the wino after they spend all night trying ''not'' to watch ''Frankenstein''.
* LamazeClass: The "Natural Childbirth" routine. Cosby seems to enjoy his role much more than his wife does, even doing "macho breathing" along with her and cheering, "Push 'em out, shove 'em out, waaay out!" Trying to apply this approach in the delivery room of the hospital, however, was rather less successful.
* TheMagicPokerEquation: Granted it was blackjack, but Bill recounts a time in Vegas where a fellow gambler had lost seventeen games in a row. She had twenty, and the dealer was showing a face card. She demanded another card. The dealer even protested, but she insisted.
-->"And... *bam!* '''''Ace.'''''
* ManipulativeEditing: The album version of ''Himself'' is seriously chopped down from the actual performance. The entire skit on drugs is removed, and many of the other tracks are abridged. But perhaps the most egreious edits are: at one point, a flubbed line about "brain damage" (see below) is re-dubbed, and in the "chocolate cake for breakfast" skit, his accidental reference to being awakened at 4 AM instead of 6 has the correct time of "6 o'clock in the morning" looped in.
* MDEnvy: In a skit from ''Wonderfulness'' describing the day he had his tonsils removed, the young Cosby addresses an orderly: "Hey, you! Almost a doctor!"
* NotMakingThisUpDisclaimer: Bill got annoyed with people constantly asking him if he really played football in college. He eventually created a whole routine about a CurbStompBattle that Temple was on the receiving end of against rival school Hofstra just to prove he really played.
-->"I played football for Temple University. And it's the truth, see! Don't keep asking me 'did you really play?' ''Yes'', I really played! [[GloryDays At one time, I had a beautiful body]]!"
* ObfuscatingStupidity: In ''Himself'', Bill suggests this is the attitude many fathers take towards things they don't want to do.
-->"Fathers are the geniuses of the house. Because only a person as intelligent as we could fake such stupidity. Think about your father! He doesn't know where anything is! You ask him to do something, he messes it up! ... That's a genius at work! Because he doesn't want to do it! And he knows someone will be coming soon to stop him from doing it! ... So you see, we are dumb, but we are not so dumb. It takes great courage and work to keep from working."
* OneHitWonder: In 1967, he had a #4 pop hit with "[[http://www.youtube.com/watch?v=pQmNivXjoo8 Little Ole Man (Uptight — Everything's Alright)]]."
* OneWingedAngel: Played straight:
-->"I've often heard of people having a conniption, but I'd never seen one. You don't ''wanna'' see 'em! My wife's face...split. The skin and hair split and came off of her face so that there was nothing except the skull! And orange light came out of her hair and it lit all around! And fire shot from her eye sockets and began to burn my stomach! And she said, '[[ItMakesSenseInContext Where did they get chocolate cake from!?!?]]'"
* PrecisionFStrike: Known for being very clean in his comedy both in the content and the language, but he will occasionally swear to emphasize a point. From "Himself":
-->"I asked a friend, 'What is it about cocaine that makes it so wonderful?' And he said 'Well, it intensifies your personality.' To which I responded, [[SophisticatedAsHell 'Yes, but what if you're an asshole?']]"
** Cosby also says "shit" at one point in that same skit, which is perhaps the only time he ever said that word onstage.
* PunctuatedForEmphasis: As part of his "Natural Childbirth" routine, when he talks about his wife actually giving birth:
-->"Then my wife stood up. In the stirrups. [[BrickJoke Grabbed my bottom lip.]] And said, 'I! WANT! MORPHINE!!!'"
* RecordedAndStandUpComedy: Which eventually turned into "sit-down comedy", as Cosby took to performing while seated in a chair.
* RevisitingTheRoots:
** ''Series/TheCosbyShow'' was filmed in studios in Brooklyn and Queens, more closely matching the location of the story, rather than NBC's typical Los Angeles locations, on Cosby's insistence.
** ''My Father Confused Me -- What Must I Do?'' contains a number of obscure routines which seem to delve into issues a bit more oriented to black life, including one about "dudes on dope." One telling example is an early version of "The Dentist" delivered quite differently than his more well-known ''Himself'' version.
* RunningGag: Throughout ''Bill Cosby: Himself'', his kids answering nearly every question with, "I don't know." He refers to it as "brain damage". This shows up again on ''Those of You With or Without Children, You'll Understand'' a few years later.
* SecretWeapon: Buck Buck, a game about who can get dogpiled longer without falling down. Bill and his friends had crazy endurance, and so did the kids from [[WrongSideOfTheTracks "the rough part of town"]], (to the point of [[NoSell no-selling]] it)... thing is, those kids didn't have Fat Albert.
-->[[OhCrap "We give! He ain't fallin' on us!"]]
* ShootTheMedicFirst: The punchline to his "Medic!" routine on ''AudioPlay/IStartedOutAsAChild''.
* ShoutOut: A meta example. In a skit on ''Bill Cosby: Himself'', Cosby uses his Mushmouth voice for a dentist patient who has just taken Novocain.
* SoundtrackDissonance: The opening segment of ''Bill Cosby: Himself'', on the original release, was a parody of Grover Washington Jr.'s "Just the Two of Us" sung by Cosby himself, titled "[[https://www.youtube.com/watch?v=wvq9LbRes80 Just the Slew of Us]]". On the original VHS and 1990s cable releases, it was replaced with an example of this trope: a slow, somber ballad called "[[https://www.youtube.com/watch?v=lOm5Bjye5K0 It Was a Good Idea at the Time]]".
* SuddenlyShouting: In "Bill Cosby: Himself", Cosby discusses having to make breakfast for his children at 6 AM. He randomly shouts certain words:
--> '''Cosby''': So I got up. Needless to say, I was angry. And I went downstairs without putting on my robe. Standing there in my pajamas, and I'm talking to myself. I said, "Get these, go down and cook breakfast, but it's six o'clock in the morning", and I slam the pans down. '''Blam!''' On the stove. I slam them down and go to the refrigerator and look around and I get to the damn '''bacon''' and the '''sausage''', cooking breakfast, six o'''blam!!!''' in the morning, and I grab the- [[SubvertedTrope you have to be careful with eggs.]] '''Got'''! to have to cook '''breakfast'''! '''Boom!'''
* TakeThat: In his "200 MPH" routine, he talks about when he bought a custom Cobra sports car from Cobra founder Carroll Shelby, that would go over 200 miles per hour. After a nearly lethal test drive that thoroughly unnerved Cosby (the engine was so powerful that Cosby felt as though he was taking his life in his hands when he drove it), he got as far away from the car as he could, and told the dealer, "Take the keys and this car, it's all paid for, and you give it to George Wallace."[[note]]The album was recorded in 1968, when noted pro-segregationist George Wallace was running unsuccessfully for President.[[/note]]
* TemptingFate: Cosby recalls in one story about how his mother caught him and his brother repeating some curse words that they heard from their father, only to have her yell at them, "WHERE DID YOU GET THAT FROM?" Cosby then vows to never say that to his own kids. And keeps that vow, until his young daughter (maybe first-grade age) hikes up her dress at the dinner table and shouts, "See my titties?" Cosby's response? "WHERE DID YOU GET THAT FROM?!?" Then he escalates it by going to see the school's principal the next day, figuring she learned it at school.
* ThisIsMySide: Figures prominently on the title track of ''To Russell, My Brother, Whom I Slept With''. Even after Dad orders Bill and Russell to get out of bed and stand in their room for the rest of the night, Bill warns Russell not to move onto his side of the ''floor''.
* {{Unishment}}: The "Chocolate Cake for Breakfast" routine. Bill screws up making breakfast so badly that his wife sends him to his room. Seeing as how it was 6 in the morning, and she had woken him up to make breakfast in the first place, Bill was more than happy to go. In fact, Bill even suggests [[ObfuscatingStupidity he did that on purpose]].
-->"So you see, we are dumb, but we are not so dumb. It takes great courage and work to keep from working."
* VocalDissonance: Whenever Cosby does a lower-pitched voice in his stand-up act, since it contrasts with his usual higher-pitched voice. An example is the dentist in the "numb mouth" sketch.
* VivaLasVegas: Several bits on his "For Adults Only" album concern Las Vegas and gambling.
* WhenIWasYourAge:
** During ''Himself'', Bill mentions that his parents have now become grandparents, and his father will willingly give out money to his grandchildren -- but when Bill was his children's age, in response to any request for funds, the same man "would tell [Bill] his life story. And this man ''never'' told a happy story. For 50 cents, there never was happiness!" Among other things, Bill recalls his father saying something along the lines of the usual: "I had to walk five miles to school! Uphill! Both ways! In 5 feet of snow! And I was thankful!"
** Also, no matter how his father suffered, he'd always say, "And I was thankful to get it!" For 30 years, Bill claims his father told him, all he had to eat was dirt. "And I was thankful to eat that dirt!"
** At another point, Bill recalls asking his father for a dollar for his school picnic. His father replied by explaining how he once killed a grizzly bear with his loose-leaf notebook.
* ZanyScheme: During his "Street Football" routine from ''AudioPlay/IStartedOutAsAChild'':
--> ''Here's a guy with an ingenious mind. He'd call a football play like this...."Now, listen to this, now. Uh, Arnie, go down, uh, ten steps and cut left behind the black Chevy. Filbert, you run down to my house and wait in the living room. Cosby, you go down to 3rd Street, catch the "J" bus. Have him open the doors at 19th Street. I'll fake it to you." They always have one fat kid they never throw it to, says, "What about me?" He says, "You go long."''
