Abbott and Costello's famous "Who's on First?" routine still stands as one of the greatest comedy sketches of all time. It was a feat of rapid-fire dialogue, flawless comedic timing and devastating wit.
But could you do it without saying a word?

It was a link to an American Sign Language (ASL) version of the skit, sent by a friend. It was amazing, Pesca says.
