What do you do when someone asks "what's an acting performance so good you forgot it was acting?" It's obvious that you just show them this funny video clip from a movie. Except, I don't even know what movie it is, but the video itself is good enough that we should all be looking it up.

This movie clip shows a woman falling off over a banister and a man rushing to catch her. Except, she appears to be falling for what seems to be 8 to 10 business days, and somehow the man still gets there in time.

WATCH and enjoy:

Now it's your turn! Tell us the best acting you've ever seen.
