Brian Doyle Murray
Bill Murray's brother had a short stint on SNL during the 1981-82 season. Unlike Bill, he just didn't stick. It's okay because his little bro gave him work in Groundhogs Day some years later.

Julia Louis-Dreyfus
She was on SNL for three years before leaving the show, and is tied with Abby Elliot as the youngest female cast member to ever be on the show. Sadly, she was never to be heard from again. JK, SEINFELD!
