Gracie Allen's airy lack of concern with reality was unmatched.

L&H then the Stooges, haven't really seen a lot of the other two.

Very dated (early 1900s) but they were very popular.

I turned my two sons on to the Marx Brothers when they were pretty young. We still enjoy watching them together when we can.

Abbot & Costello

Then

the Marx Brothers

Laurel & Hardy

Bowery Boys

Three Stooges

No mention of Martin and Lewis. When Jerry Lewis (or is it Louis) was funny.

I also thought the old Bob and Ray radio show was great with all their skits. Wally Ballou, Mary Backstage Noble Wife (a play on the Broadway show Mary Noble, Backstage Wife.

Just my personal opinion, though. I know some people liked him, but that voice always made me want to run screaming from the room.

However, I am a huge fan of Dean Martin, and I guess I thought he was better by himself.

and just quietly eating dinner and leaving.

Had no idea lol

No contest

BAD!!! Bad Auntie Beeb! Not allowing Goon Shows on the Internet!

Also tops, The Marx Brothers.

ALL were great in their own respects

My mother hated them, so of course I loved them.

Genius.

really stupid elmer fudd.

all four acts mentioned were great for their own reasons. we watch abbott & costello meet frankenstein every halloween, my kid loves it.

Tim Conway, Harvey Korman, and Carol Burnett! OMG, they were hysterical to watch!!

Of the older ones, I'd take the Marx Brothers.

after that was Abbott & Costello, The Three Stooges and Laurel and Hardy.

Groucho tips the scale. Marx Brothers it is.

People forget they were more popular than FRIENDS and BIG BANG THEORY, combined.

Cheech and Chong were good too.

Bob Elliot and Ray Goulding were on the radio and early tv for 5 decades.

I never enjoyed acts where people (appear to) physically injure each other.

Smothers brothers.

Marx Bros for the old, Firesign Theatre for the modern.

Trump and Sarah.

It's not something I've thought about much, but the OP certainly triggered the question. Maybe Penn and Tellar, but that's about it.

Bouncer: Hey, Baravelli!

Baravelli: Whadaya want?

Bouncer: Watch the door for a few minutes. And don't let anyone in without the password.

Baravelli: Alright, what is it?

Bouncer: "Swordfish" is the password, d'ya understand?

Baravelli: Okay, I got it.

Bouncer: Well, what is it?

Baravelli: Password.

Bouncer: Swordfish! Swordfish!

Baravelli: Alrighta! Swordfisha! Swordfish!

Bouncer: Aahh...

Baravelli: (roughly interpreted) Piazza mosco santa rumbolla fatcha duzzi patsi!

There's a knock at the door. Baravelli opens the peephole.

Baravelli: Who are you?

Wagstaff: I'm fine, thanks. Who are you?

Baravelli: I'm fine too, but you can't come in unless you give the password.

Wagstaff: Well, what is the password?

Baravelli: Oh no, you gotta tell me! (pause) Hey, I tell you what I do...I give you three guesses...It's the name of a fish...

Wagstaff: Is it Mary?

Baravelli: Ha, ha! Atsa no fish!

Wagstaff: She isn't? Well, she drinks like one. Let me see...Is it sturgeon?

Baravelli: Hey, you're crazy! A sturgeon, he's a doctor cuts you open whena you sick. Now I give you one more chance.

Wagstaff: I got it! Haddock!

Baravelli: Atsa funny, I gotta haddock too.

Wagstaff: What do you take for a haddock?

Baravelli: Well now, sometimes I take aspirin, sometimes I takea calomel.

Wagstaff: Say, I'd walk a mile for a calomel.

Baravelli: You mean chocolate calomel. I like that too, but you no guess it. (Slams door. Wagstaff knocks again. Baravelli opens the peephole again.) Hey, whatsa matta? You no understand English? You can't come in here unless you say swordfish! Now, I give you one more guess.

Wagstaff: (thinking) Swordfish...swordfish...I think I got it! Is it swordfish?

Baravelli: Ha! That's it! You guess it!

After the two settle themselves at the bar, the following conversation ensues.

Wagstaff: Well let's get down to business. I'm looking for two football players who always hang around here.

Baravelli: We always hang around here, but we don't...

Wagstaff: (interrupting) Well, that's all I wanted to know. I'm Professor Wagstaff of Huxley College.

Baravelli: That means nothing to me.

Wagstaff: Well, it doesn't mean anything to me either. I'll try it over again. I'm Professor Huxley of Wagstaff College.

Baravelli: Well you didn't stay at the other college very long.

Wagstaff: You're heading for a breakdown. Why don't you pull yourself to pieces?

Baravelli: I'll talk it over with my partner.

Wagstaff: In case I never see you again, which would add ten years to my life, what would you fellows want to play football?

Baravelli: Wella first we wanna football.

Wagstaff: Well, I don't know if we've got a football. But if I could find one, would you be interested? I don't want a hasty answer, just sleep on it.

Baravelli: I no think I can sleep on a football.

Bartender: Who's gonna settle for these drinks?

Baravelli: (Flips coin and hides the result. To Wagstaff, he says,) Your stuck.

Wagstaff: (To bartender.) Can you cash a check for fifteen dollars and twenty-two cents?

Bartender: Sure. (Opens drawer and counts out money.) Five, ten, fifteen, and twenty-two.

Wagstaff: Thanks. As soon as I get a check for fifteen dollars and twenty-two cents, I'll send it to you. (Flees with Baravelli.) Swordfish!

Bob and Ray

The Smothers Brothers

Carl Reiner and Mel Brooks

My mom loved the Bowery Boys, but I don't remember them and should revisit.

Boris and Natasha, Rocky and Bullwinkle

Franken and Davis
Stiller and Meara

they had the physical comedy and also had some great lines of dialogue that often got missed in all the physical stuff.
Curly was hard to top.

Burns and Allen and the Marx brothers tie for 2nd for me.
ETA:
Monty Python should get a message someplace.
When I think about it they were actually probably the all around best.

Bob Elliot and Ray Goulding. Comic geniuses on radio and the stage!
