Gable Ness Nealon was born Monday night at St. John's Health Center in Santa Monica, Nealon publicist Meredith O' Sullivan said in a statement.

Nealon, 53, gained fame during nine seasons on NBC's "Saturday Night Live." The standup comic's current stint on Showtime's Golden Globe-nominated "Weeds" features him as a pot-smoking city councilman, reports AP.
