Here’s a video from TMZ with Matthew Perry sitting in a taxi and playing a prank: http://www.tmz.com 

The caption reads: So a brunette (Brooke Shields), a blonde (Kim Raver) and an ex-sitcom star (Matthew Perry) walk out of an Upper East Side karaoke bar… (Also present is Timothy Busfield). This was after Matthew Perry attended the NBC, IMG & Saks Fifth Avenue Celebrates “Lipstick Jungle” at Saks Fifth Avenue in New York City.

Unbelievably, Perry was convinced to give up his cab seat to “Studio 60 on the Sunset Strip” co-star, Timothy Busfield. Matt got the last laugh — check out who he went home with!

Thanks Martha for the link!
