Another Comedian Ruined By Parenthood
AUSTIN, TX—Ed Corgi, once hailed as one of the area’s funniest and most ribald stand-up comedians, has lapsed into mediocrity due to the 2003 birth of his daughter Grace, a friend reported. “Ed used to get up there and just spit venom against the entire world until the crowd was dying,” fellow comic Rick Haste said. “Last week, I saw him do a bit about grape juice and another about how hard it is to get a stroller in a car trunk. He did swear a lot as he pantomimed folding the stroller, but still.” Corgi’s new sitcom Grape Juice is currently in development at ABC.
