Any number of scenes between Groucho Marx and Margaret Dumont, or between Groucho, Chico and Harpo. Harpo Marx in general.

You should drop by Chez Zmayhem on a Sunday afternoon as Emmett almost always has a Marx Brothers movie in by then. My favorite scene is probably the duel with the lemonade vendor in Duck Soup. Harpo's anarchy is right off the charts.

That is possibly one of my favorite Marx Bros scenes ever.

Y'all've hit most of my favorite Marx Brothers & Preston Sturges scenes.

One of my all-time favorite TV scenes was in the second episode of Freaks and Geeks, when Bill accidentally squirts himself in the crotch with beer. Of course, any scene with Bill in it was comedy gold. Other favorite Freaks and Geeks scenes:

• Mr. Weir telling the kids about losing his virginity in Korea ("I wish I could get that five dollars back.");
• Mr. Rosso's inappropriate confessionts ("And when I say he beat the living crap out of me, I mean the living crap." "No need to explain; I got it on in a van at Woodstock");
• Sam streaking;
• Sam buying a jumpsuit from Joel Hodgson (Bill: "Superstud, Sam! Go for superstud!") (which reminds me, Veronica Mars's buddy Wallace plays a mathlete in that episode);
• Kim Kelly's parents having a huge fight in front of Lindsay, culminating in her tearfully telling Lindsay, "You're my only friend, and you're a total loser.";
• Nick singing to Lindsay;
• Nick in his speedo;
• Nick disco-dancing;
• Nick's song "Lady L";
• Nick taking handfuls of fruit rollups from the Weirs;
• Nick angling for an invitation to dinner ("Let me guess: meat?")
• Carlos the Dwarf.

Other favorite funny movies or tv shows:

• Jesus washing his bowling ball in The Big Lebowski;
• Steve Martin escaping from the sniper in The Jerk;
• So much of Mr. Show - Three Times One Minus One, Jeepers Creepers: Semi-Star, Fuzz: The Musical, Drugachusetts, Indomitable Spirit ("I'm Fran. I'm a woman!"), Philouza, The Satanic Broadcast Network ("The doctors say... I am lazy."), America Blows Up The Moon, Wyckyd Sceptre, Tittanica, The Story of Everest, Choo-Choo The Hurky-Jerky Dancer (which I could watch forever), Taint Palace;
• The Office ("Free Love on the Free Love Freeway" and "...and people say she's just a pair of tits" may be my favorite moments of the show);
• Bad Santa. The whole damn movie;
• Bobby on Ritalin on The King of the Hill ("There's some milk in the fridge that's about to go bad... and there it goes.");
• Jackie Chan's first demonstration of drunken boxing in Drunken Master II;
• That dialogue between Woody Allen and Diane Keaton in Love and Death that manages to reference every major work of Russian fiction in about 20 seconds;
• MST3K doing the short "Catching Trouble" about a redneck trapping wild animals in the Everglades.

Some people kill evil. Some machines kill fascists. I kill discussions.

Any number of scenes between Groucho Marx and Margaret Dumont, or between Groucho, Chico and Harpo. Harpo Marx in general.

Yes, this. I need to buy my own copy of the Marx Brothers box set, since I can't really steal my Dad's. (I gave it to him, so I'd feel bad scampering off with it.)

The "If nobody has any objections, I believe I might be of service." scene during the walk-off in Zoolander.

"Oh good, my dog found the chainsaw" from Lilo and Stitch.

Almost everything in Young Frankenstein.

Morticia's line "You have enslaved him. You have placed him under some strange sexual spell. I respect that. But please, may we see him? " from Addams Family Values.

... okay, now I want to go home and watch movies.

"CK DEXTER HAAAAAAAAAAAAAAAAAAAAAAAAVEN!"

When Cary Grant pushes Katherine Hepburn down by her FACE.

"Oh good, my dog found the chainsaw" from Lilo and Stitch.

YES.

Bobby on Ritalin on The King of the Hill ("There's some milk in the fridge that's about to go bad... and there it goes.")

Oh. My. God. YES!

"Uncle Fucka" during the South Park movie. I cried with laughter. Laughed more and more during the movie, but that one was the only part that made me cry.

On "Friends," the Thanksgiving episode where Rachel makes the British trifle, but the pages get stuck together in the cookbook, so it has beef in it.

Ross' line, as soon as Rachel leaves the room: "It tastes like feet!" His delivery kills me, no matter how many times I've seen it.

His delivery kills me, no matter how many times I've seen it.

That episode always cracks me up.

"What's not to like? Jam? Good. Custard? Good. Meat? Gooooood."

On "Friends," the Thanksgiving episode where Rachel makes the British trifle, but the pages get stuck together in the cookbook, so it has beef in it.

And Joey's, "Beef, good. Jam, GOOOOOOOOOOD!"

(ETA: Or, what Dana said. Either way, it's the drawn-out "goooood" that makes the moment.)
