You Don't Know Jack

The off-screen host's irreverent jokes are often laced with innuendo and sexual references, such as how many "bones" have been in Charlie Sheen's so-called "goddesses" and his fear of "dying with nuts in my mouth" after a question about allergies.

One of the first words you hear in one of the levels is "butthole" -- but more offensive words like "s--t" and "f--k" are spoken, but bleeped out (barely) for comedic value.

Alcohol is mentioned occasionally in the questions, but isn't a focus of the game. One question has to do with psilocybe semilanceata mushrooms -- which are the mood-altering variety. 

Parents need to know that You Don't Know Jack is a comedic trivia game that blends pop culture with obscure trivia. The game is fast-paced and funny, but many questions are much too risque for young children, with sexual euphemisms and suggestive language. The game, in the guise of a TV show, will taunt you mercilessly if you miss an answer or if your score is low. No subject is off limits, either, as news events like Charlie Sheen's tirades and Elizabeth Taylor's death are mocked. As for the questions, they might have a foot in current events, but they're often very difficult -- and might teach players something in the process. You Don't Know Jack HD is available for the iPad.
