While Collins' talent was apparent even back then, according to a 1996 Los Angeles Times article, Segel also made quite a name for himself on the court. Not only did he entertain with his Arnold Schwarzenegger and Kermit the Frog impressions, but Segel earned the nickname "Doctor Dunk" after completing a two-handed dunk with the front of his jersey pulled over his head. "I'm not nearly as skilled a basketball player as some of the other guys. But I have a lot of bravado," Segel told the paper in 1996.
