Remember that Match Game questions don't have a single correct answer; they have a fill-in-the-blank question where the panel fills the blank and the contestant tries to guess how the panel answered it. It's best if the question can generate a laugh. The standard example is, "The Starfleet admiral said, 'Captain Kirk has the biggest ___ in Starfleet!'"
Update, 23 June 1300: Turned comment moderation on here and on the other thread on which people have been posting questions. I'd prefer they be e-mailed to me (my lj handle @livejournal.com will work or you can LJ message me). I'll not clear posts with actual questions in them.
