Is this a movie quote or did I make it up?

I remember a quote from a movie or possibly TV show where a guy says that he can fit an entire cat/kitten in his mouth.

A woman says something like asking "how can you put a cat in your mouth?"

And he replies, "Simple, you just told their little legs up like a folding table." While mimicking it with his fingers.

Did I make that entire scene up, or is it from a movie/TV show?
