Yes! Actually there is!
On one episode, Joey tries to get the part of a 19-year old. He walks out of his room dressed as a "punk" and notices Chandler playing a video game. Joey says something like, "You playin' Playstation? Playstation's whack, man!" (Heheh...I loved that.)
I looked closely at the TV when Chandler was talking, and actually he was playing N64! Mario Kart 64, to be exact. If I remember correctly, he was DK and racing on DK's Jungle Parkway!
(Maybe Deezer should add this to the thousands of Mario refernces.)
