They had one inside joke that they did a lot, and Matthew Perry did it, and I thought, ‘If I can make him laugh, it’s just going to feel so good.’ So he would — you couldn’t do it now, you’d get canceled — he would run and throw himself on the floor in front of a girl and pretend to look up her skirt.

Brooke Shields is remembering the risqué stunt that she pulled while on the 'Friends' set that made Matthew Perry burst out laughing: 'I look like a crazy person!'

Brooke Shields on Monday recalled her cameo on “Friends” and the lengths she went to in a bid to get the cast of the hit sitcom to like her. The actor and model — who played Erica, who stalked Matt LeBlanc’s Joey Tribbiani in a 1996 episode of the second season — said she even copied a gag that the late Matthew Perry (who played Chandler Bing) used to pull to try to connect with the show’s stars.
