The song from the same episode, even though it was technically lip-synching.
That song's meta-awesome too:
Sean Szeles (storyboard artist and writer): I also wrote the songs that were featured in this episode and I thought they were going to be re-recorded by the composers, but they just kept my versions in. I just recorded everything in my apartment playing the different parts and threw a drum loop on there.
It might not have been. Mordecai said he did start beating up the boy in the costume, it just wasn't as totally Bad Ass as Rigby was dreaming it. Still awesome though.
"They say this city's tough. But I'm tougher."
The fight against Snowballs the Ice Monster.
Skips gunning it in the golf cart to retrieve the cover of the Book of Park Records. Sounds pretty normal for Regular Show, right? Well you're forgetting that Skips did it with a broken leg.
Rigby using his laser pointer as a machine gun on Peeps.
Pops' speech in Dizzy.
Mordecai and Rigby defeating GBF at "Broken Bonez" and getting the universal high score.
Mordecai, Rigby, and the rest of the gang defeating the humanoid TV with good ol' fashioned beat-em-up skills in "Rage Against the Television".
They knew his weakness: furniture. Still, it was a pretty awesome fight.
During the fight "The Hammer" appears and everyone runs but Skips he just raises his fist and gets ready to rock, after he gets swatted aside (a Crowning Moment in of itself). Mordecai and Skips just get up to try and wail on him.
Not to mention that they basically used the stairwell as a furniture form of a machine gun!
Mordecai pulling the Immunity Sword, which is immune to all rule changes, out of Hammer Space and stabbing the nefarious Game Master of the Realm of Darthon with it.
What makes this even better is that we've seen in episodes like this and 'But I Have a Receipt' that Mordecai isn't very good at using his imagination. (When asked to imagine the golf cart in the aforementioned episode, he could only remember the part they sat in.) The fact that he actually gets better at it than Rigby near the end is saying something.
The fact that he realized how to deal with all the rule changes (changing the rules himself) is pretty awesome in of itself.
Benson arriving in "This Is My Jam" and pretty much saving the day by playing the drums awesomely.
Compounded by the fact that, besides one deleted scene in "Mordecai and the Rigbys", Benson wasn't even hinted to play music.
It's the Brain Explosion album Mordecai plays: the song is quite clearly a knockoff of "20 Jazz Funk Greats."
At the end of the episode where Rigby is jinxed, Mordecai and Rigby say the same thing at once again. Mordecai gets jinxed. Rigby punches him when he talks, but it doesn't do anything. So he jabs Mordecai in the eye.
Mordecai, Rigby, Muscle Man and Skips defeating the zombies with shot puts and javelins in "Grave Sights".
Special mention goes to Skips driving a vaulting pole through about four zombies and then beheading them by stomping their heads off. Skips has been taking some cues from the Brock Samson School of Kicking Ass.
The fact that the entire fighting sequence in "Grave Sights" pretty much coincided and even at one point merged together with the movie. And these lines:
Mordecai: Okay you lousy undead freaks-
Hero Dude *
Stated in the credits.
: You may have taken a lot from me, but if you think you're going to deprive me of my-
Mordecai: paid day off-
Hero Dude & Mordecai: You're sorely mistaken.
Pops winning the ladder match in "Really Real Wrestling".
Everything Pops does in that episode is awesome.
Skips arm-wrestling DEATH for Rigby's soul. Said arm-wrestling match opens up a black hole that spews out lightning.
Earlier in the episode, Skips calls out Rigby on cheating, then beats him at arm wrestling so hard he literally dies.
And they play DIES IRAE in that scene.
Muscle Man and High-Five Ghost beating down the Night Owl's minions as they race towards the time machine. Muscle Man gets another one at the end when he punches out the Night Owl for what he was planning to do to them.
In one episode, Mordecai and Rigby take care of a bunch of stranded baby ducks. However, a creepy man steals them, forcing the two and the ducks' mother to chase him. The creep takes out a sword cane to use on the three, when suddenly the baby ducks, angered at seeing both their birth mother and their adoptive mothers in danger, fuse to create a giant man with a duck head, who uses a flaming karate chop to slice the man in half, causing an atomic explosion.
Wedgie Ninja's Heroic Sacrifice in "Go Viral". Just as the Warden of the Internet is about to catch Mordecai, Rigby, and Pops, he gives her a wedgie and holds her back, allowing them to escape. He keeps it up until the Warden explodes!
The finale of "Skunked" with Rigby fighting the Wereskunk and Mordecai pulling a Big Damn Heroes by plowing through the wall in the cart, allowing Rigby to cure himself and take out the Wereskunk. The entire episode probably counts for the writers, as what could've been another simple comedy episode was actually rather dramatic and well done.
Rigby: SPLIT THIS.
Earlier in the episode, when the Wereskunk is choking Rigby (turning into a hulking form in the process), Mordecai rushes in with a shovel and threatening to beat the tar out of him if he doesn't let Rigby go.
Benson (also possibly all the characters) in "Karaoke Video" pulls a pretty good awesome moment after the tape lands near him and gets punched during the karaoke brawl by the Jerkass owner. Take into account that Benson was watching the entire fight up til now.
Benson: YOU WANT IT?! FINE! TAKE IT THEN! *smashes the karaoke tape off the owner's face, knocking him out and destroying the tape in the process.
Also from that episode, the whole cast pulling out some awesome fighting skills in the brawl, along with Muscle Man chugging on gravy while doing so, Pops knocking out a guy in one shot all to Pops singingFootloose.
Season 3
Benson's mastery of Stick Hockey in the titular episode.
Mordecai and Rigby aren't slouches either, making it to the finals under their own power.
In "Bet To Be Blonde" Rigby and Mordecai not only escape the blonds, but escape with a self destructing ring that Mordecai sets off that kills the blonds and sends Mordecai and Rigby flying up to the surface in a elevator.
Rigby gets one in the Halloween Special by telling the ghost story which manages to scare everyone into complete silence (except Muscleman, but he just nitpicked the least frightening part of the story).
If it was even Rigby to begin with...
Mordecai smashing the Jersey Devil-like creature, who was chasing them, with a lantern in the camping episode.
How does Regular Show make basketball awesome? By giving Mordecai, Rigby, and Muscle Man super basketball powers, taking to space, and having Mordecai win the game with a slam dunk, from space! A dunk so epic, it destroys the basketball court, and much of the surrounding area.
Benson got his second MoA of season 3 in "Cool Bikes" by attacking the judge and allowing Mordecai and Rigby to escape their certain deaths for being too cool.
Pops, Mordecai and Rigby sticking together in their crew and defeating an opposing rap crew with fine poetry, by praise. Great way to teach about moral victory.
The Disney Acid Sequence at the end of "Weekend at Benson's" was one for the animators.
Benson freaking exploding at Mordecai and Rigby during "Think Positive".
Note, that his rage was so large and built up, that when releasing it, he makes Mordecai and Rigby go deaf and lay in a crater.
Mordecai punching Benson in "Eggsellent" after he made an insensitive remark about Rigby (who was in a coma).
Muscle Man's Unstoppable Rage in "Big Winner". The guy tears through wave after wave of Lottery Enforcement Officials, SWAT vans, even tanks. It would seem that he could even defeat all the officers if Mordecai and Rigby hadn't interrupted him.
Mordecai and Rigby whopping up on Clorgvain, with the Fists Of Justice.
Rigby pulling off one hell of a Determinator act to keep his job in "Muscle Mentor".
The entire climax of "Trucker Hall of Fame".
Fancy Restaurant - when the snooty waiters nearly kick out Muscle Man, Starla, and her parents for Muscle Man not being fancy, the parents reveal themselves to be just as tough as Muscle Man, and they all join forces to take down all the waiters.
Rigby actually landing an effective punch on Mordecai, during "The Best VHS In The World".
Muscle Man defeating Gene in "Prankless". The best part is that he did it all with mirrors.
Mordecai taking down Death Bear. Bonus points for him having been scared of Death Bear since he was a kid.
Death Bear using Kung-Fu on animal control.
Season 4
"Exit 9B". Just... "Exit 9B". It is perhaps the best episode yet, and a treat to any fan of the show, with Call Backs and Cameos aplenty.
The epic smackdown between The Park Crew & Friends VS Garret Bobby Ferguson Jr's army of baddies.
Special mention goes to Super-Duck duking it out with Susan.
Benson pulling off the world's most epic drum solo during "150-Piece Kit"
The Christmas Special. While Christmas Eve/Sarajevo 12/24 is playing, Mordecai and Rigby save Christmas by leaving the evil Elf to his doom into a lava pit with the cursed present box, and Mordecai does so by wishing a flying skateboard to save himself and Rigby from the plunge.
And prior to this, Pops wrestled a polar bear. And won!
Sandwich Of Death: THE RETURN OF DEATH KWON DO!
Margaret: "Have a nice week, diaper boy"
"A Bunch Of Full Grown Geese". Highlights include:
Mega Duck Vs Mega Geese, round 1.
Round two, which starts with a Call Back-laden Powerup Seqeunce, set to "The Touch".
