Celebrity Guest of the Day: Bill Nye Appears on 'Whose Line is it Anyway'

Bill! Bill! Bill! Bill!

Bill Nye appeared on Whose Line is is Anyway and showed that this Science Guy has some serious comedy chops.

With fan favorites, Ryan Stiles and Colin Mochrie, the trio played a game where Stiles' hands were provided by Mochrie. And they were all in space because duh—science.

Things got hilarious very quickly, with Bill Nye having to taste some of the "space food."

Ryan ended the skit on this final gross note.
