GSN is airing John's first Hollywood Squares (1998-2004 version with Tom Bergeron) week from 2000 this week at 11am and 1:30am ET from Tuesday-Thursday. The 1:30am one is an encore of the 11am airing. For some reason GSN is only airing three of five episodes.

#2171, #2173, and #2174 (so day 1, 3, and 4)
Kelly Hu, Charlie Schlatter, Star Jones, Caroline Rhea, Deborah Norville, Bruce Vilanch, Whoopi Goldberg, John Ritter, Markie Post

John went on to do many more weeks from 2000-2003, but this week was his first one. Watch!
