Cracks me up every time I see it. Especially the part with the scissors!
From the "Three Valentines" episode of Frasier. One of the very best comedic sequences ever and I don't think this is hyperbole Not one word of dialogue. It meant more to regular viewers, but a casual drop in could still be floored by its genius. And it also helps to have a cute animal accompaniment.
It started off slow, and I almost ditched it, but I'm glad I held on. My lover thought I was having a seizure I was laughing so hard.
