Not exactly fisticuffs, but:
My Three Sons, Uncle Charlie vs. I Love Lucy’s, Fred Mertz
(At the downtown Bryant Park grocery store, Steve Douglas strolls absentmindedly behind Uncle Charlie, smoking a pipe)
Steve Douglas: Say, Charlie, what aisle is the pipe tobacco on?
Uncle Charlie: Steve, you idiot, this is a grocery store, not a tobacco shop.
Steve Douglas (takes long puff from his pipe): That’s an astute observation, Charley, I’ll keep that in mind.
Uncle Charlie: Follow me, numb-scull, we gotta go down aisle 6 for the dog food. Your bastard son Ernie keeps forgetting to lock the damn doggie-door at night and Tramp knocked up the neighbor’s poodle again. Now we got a bunch of puppies to feed.
(Rounding aisle 6, Charley halts his cart abruptly)
Uncle Charlie: Hey, Lady, move your fat ass, don’t ya see your blocking traffic!
Fred Mertz (turns around, snarls lips, taps Uncle Charlie hard on the shoulder): Who, you callin’ Lady, bub, that’s my old battle ax you’re talkin’ to!
(the situation escalates aggressively. Sounds: glass breaking; metalic schwick)
Steve Douglas: (takes long puff on pipe, exhales a cloud of smoke) Now Charlie, let’s just calm down a bit and put down that jagged bottle. Look here, you’ve spilled ketchup all over the floor when you broke it. I’ll find you a mop. (Steve wanders absentmindedly off camera).
Ethel Mertz: Fred, put down that switchblade this instant, you old fart!
Fred Mertz: Aw, shut up, Ethel! (backhands Ethel, dropping her to the floor with bloodied mouth)
(Rumble ensues, a la West Side Story)
Ricky Ricardo (upon seeing gore splatter to the floor): ¡Ay, caramba! I shoulda ditched the redhead long ago and stayed in Cuba!
Lucy Ricardo: WAAAAA!
(Of course, this could have played equally well using My Three Son’s Bub O’Casey, but that would be a little weird).
Benjamin Franklin from The Life and Times of Grizzly Adams vs. Eddie from Frasier
(Martin is in the kitchen making a sandwich, feeding scraps of bologna to Eddie. Scratching sounds are heard coming from the front door)
Martin: Eddie, go see who that is scratching at the door. Go on, boy!
(Eddie scampers to the front door, leaps up, mouths open the doorknob and nuzzles the door open. His back hair instantly stands on end when he see’s the guest in the hallway. Ben lumbers in)
Eddie: Bark Bark Bark Bark Bark!
Ben: Chomp/Eddie: Yelp
(Ben exits)
Martin (entering the living room): Who was at the door, Eddie? Eddie?
The crew of the Northwestern from Deadliest Catch vs.Flipper
Captain Sig Hansen: (on loudspeaker to deck): Whats the count on that last crab pot, Edgar?
Edgar Hansen: 17opilio…and what looks like the backbone of a pretty big fish. The crabs sure did a number on him! And, if I didn’t know better, I swear there’s something that looks like a human foot in there, too!
Porter Ricks (looks around the cabin, then leans toward Sig): You see my boy, Bud, lately, Sig?
