Dick Van Dyke, Tim Conway, and Carol Burnett arrive one by one for obedience school, each with a “dog” that’s invisible to us but entirely too real to them. It’s the ultimate test of physical comedy — three masters miming the world’s worst-behaved pets, and an instructor (Lyle Waggoner) who’s slowly losing his mind.

Conway is first through the door, tugging and grunting like he’s fighting a polar bear on a leash. “Control your dog!” the trainer shouts. “I meant the dog!” Conway straightens his jacket, deadpan, pretending not to notice that Bruno the beast has already dragged him halfway across the floor.

Next comes Carol Burnett, who floats in with false elegance and a leash that’s somehow longer than her patience. “Mrs. Gilda Haven,” the instructor warns, “you might consider getting a longer leash.” She smiles sweetly, oblivious as her invisible hound apparently attempts to redecorate the room.

And then — the real storm. Dick Van Dyke enters, proudly introducing his unseen companion. Within seconds, his “dog” is leaping, lunging, and turning the obedience class into a full-scale riot. The three owners tangle their leashes, stumble into one another, and wrestle their imaginary animals like cartoon rodeo clowns.

Each lesson — “Sit,” “Stay,” “Heel” — becomes a new disaster. Conway’s dog refuses to listen. Burnett’s disappears under a desk. Van Dyke’s performs interpretive chaos, hurling him across the room in bursts of perfect slapstick. Watching the three of them flail in sync is like seeing a ballet choreographed by pure mayhem.

By the time the instructor loses his cool — shouting “I never want to see either of you or your stupid dog again!” — the class has devolved into total anarchy. Conway’s mutt barks (silently), Burnett’s leash wraps around her ankles, and Van Dyke, ever the master of physical grace, topples backward in slow-motion defeat.

The sketch ends the only way it could: with the trio staggering out, their “dogs” still misbehaving, and the audience doubled over in laughter.

Because in this K-9 class, no one learns obedience — least of all the humans.

Three comedy legends, zero actual dogs, and one perfect lesson in timing: the best tricks are the ones you can’t teach. 🦴😂
