Every Valentine’s Day I remember the Fraiser that started with Niles Crane ironing his pants and ended with the blood and fire. Hysterically funny scene, and not a word was spoken.
What are some other funny scenes with no dialog?
Well, there’s the classic mirror scene with Lucille Ball and Harpo Marx (riffing on the mirror scene from Duck Soup).
Funny, I was going to come in here and post another Lucy classic, when they’re on the assembly line wrapping chocolate, but it turns out there’s a lot more dialog than I remembered. Excellent choice though spoke-.
Well, technically there was at the beginning, when Niles is on the phone . . . he’s talking to the caterer or something, and mentions how he threw a cover over his dad’s chair. Link
But I’m willing to overlook that and nominate it to win the thread. 
When Sammy Davis Jr kisses Archie Bunker on “All in the Family.”
Jack Benny was the master of the pregnant pause. I saw a few of his bits recently and laughed as much as when I first saw them.
The scene where Alex takes the cassette tape and smashes it with the meat mallet on “Family Ties.”
I guess you have to see it.
Ralph Kramden and Ed Norton learning to do the Mambo.
The scene where Carol Burnett stands at the top of the stairs in her Bob Mackie design, based on Scarlett O’Hara’s dress.
The first and last couple of seconds of this clip with Kramer and Newman making sausages are wordless, and it always makes me holler.
This breakfast scene from Morecambe & Wise is pretty classic in Britain.
The scene in Fawlty Towers where Basil is mouthing instructions to Mrs. Richards to make her think her hearing aid isn’t working.
The toilet flush from All In The Family.
3rd Rock from the Sun–the scene where Harry & Vicky devour the Thanksgiving Day leftovers, and then each other.
Along similar lines, the scene where Basil pantomimes eating for the Germans.
The scene (or long moment) from “The Dick Van Dyke Show” where Dick and Laura answer the door when the parents come calling to exchange babies. Dick has convinced himself that the babies got switched at the hospital and he and the Peters (the name of the other couple) have each other’s babies. When the Peters walk in and the live audience sees they are black, all the cast could do was stand there and let the long laugh play out.
That scene was genius. You see Dick open the door and then he drops his jaw, looks away, looks back, does a double take, keeps looking away and then back, points, and in walks Greg Morris. It was quite a silent buildup to the punchline.
Dick: Why didn’t you tell me?
Morris: And miss seeing the expression on your face?
I read the title of the thread, and before I even had a chance to mouse over I immediately thought of that scene.
I love the subtext of that. Dick couldn’t tell from Mr. Peters’ voice that he was black, but Mr. Peters was pretty darn sure that Dick was a foolish white guy.
Not a sitcom, but the classroom scene in Buffy the Vampire Slayer show “Hush”, when Giles used flash cards with stick figure drawings to explain the demons they were fighting and the groups’ various reactions (Anya eating popcorn, Buffy’s indicating her dissatisfaction with Giles’ rendering of her, etc). was pretty darn funny.
Anyone have a video clip link for this scene? I’d love to see it.
