Where to begin...
Auditions: Idiot Savants in 1996, Jeopardy! numerous times, Wheel of Fortune cattle call in Columbus, OH in 1997, Twenty-One in Chicago in 1999, Hollywood Showdown in Pittsburgh in 2000, Paranoia in 2000 (sat next to someone who won $500 on the premiere ep.), Lingo with my sister in Akron in 2006 (met Shandi; mrrrrrrrrrow!), possibly the Millionaire audition in Detroit next month but that's looking less and less likely.
In the audience: Cleveland's Academic Challenge in 1995; Wheel of Fortune at the Ohio State Fair in Columbus with Tim K. in August 1997 (aired the 2nd week of the 1997-98 season); The Price is Right in October 2001 (2 eps., aired 11/30/01 and 12/3/01); The Jeopardy! College Championship finals from UCLA in October 2001; TPiR again during GSCongress trips in 2005 and 2006; WoF again in 2006 (first 3 eps. of the 24th season); Deal or No Deal in 2006 (first ep. of 2nd season)
Played Wink's interactive games on FAM from 1993-94 just to win my sister a clarinet, never won it but got a second chance entry. In late '94, was one of 10 finalists in Interactive Boggle for a trip to FAO Schwartz in NYC and $2500 but didn't win because FAM said they'd call me back within an hour to let me know if I won. Instead, they called the next day when I was opening my first checking account, so my then 15-year-old sister played and epically failed. Also won a Double Dare video and 2 DD video games through a telephone contest in 1988, a PC on Paranoia's premiere, three gift certificates through History IQ's online game in 2000, $200 on PlayMania on 7/3/07, $50 on Bingo America (the $100,000 win ep.) and took part in 2 episodes of Anyone Can Win, winning one episode and placing 3rd on a Tournament of Champions show.
Have met numerous hosts and announcers through GSCs, got most of them to sign 8x10 photos, tickets, or other memorabilia. Had lunch with Jay Wolpert in 2001. With Aaron Sica, met John O'Hurley at a book signing in Harrisburg, PA in November 2006, got several books and an 8x10 signed. Met Paul Tapie (longtime Cash Explosion host) at a Cleveland Indians fanfest in 1994. Got Drew Carey's autograph on a TV Guide after the 1996 Cleveland Thanksgiving Parade.
And the 2 most important events: I had lunch with Chris Clementson and I gave Matt Ottinger a copy of a board game he didn't have in his collection.
