20 Mind-Blowing Facts You Didn't Know About Buffy The Vampire Slayer

15. David Boreanaz Played Pranks On Set

Buffy is a show full of humour so most of its characters wisecrack and quip all the time. That said, Angel is perhaps one of the Buffy characters least likely to crack a joke - the man who plays him, David Boreanaz, is the exact opposite, however, and was apparently the biggest prankster on set. David often ad-libbed and changed his lines to the extent that his co-stars would not know what he was going to say next. He also had the outrageous habit of pulling down his pants in between takes just to see if he could get the other actors to break out of character.
