An extremely popular video trivia game where the categories are outrageous, the questions are hilarious and the host makes fun of you when you're wrong! Everyone I know goes crazy for these games.
Have you played today's Daily DisOrDat game on the You Don't Know Jack Website?
It's called:
Spank Me! Spank Me Per the Geneva Convention!
Me DisOrDat you long time.
And it tests your knowledge of two very important topics!
