some of the categories/phrases that get distorted/perverted:

"An album cover" = I'll take anal bum cover. I've spent years trying to invent one. Failing to do so is my biggest regret. -Sean Connery

"Therapists" = The day is mine! I'll take the rapists for 200 -Connery again

"The Pen is Mightier" = "i've gotta ask you trebek, about the penis mightier. Does it work? 'Cuz I've ordered devices like that before, wasted a pretty penny, I don't mind telling you. But if the penis mightier really works, I'll order a dozen!"

"Kinds of arts" = "Lucky me, I'll take kinds of farts for 800!"

A petit dejeuner = "Gimmie Ape tit for 400" Burt Reynolds

"Famous titles" - Everybody says "Famous titties", except Sean Connery, who yells out "Dolly Parton!"

"Famous horsemen" = "Look at the category, Trebek. Whore- like your mother, and semen." -Sean Connery

How can I forget some absolute gems, such as $Texas, Below me, in doors, or the time Burt Reynolds changed his name to Turd Ferguson.

Don't forget the great gems:

Alex Trebek: "The category is 'Words that Rhyme with Dog.' And the answer is "It's been a 'Hard Day's Night.' I should be sleeping like a 'this.'"
Burt Reynolds: Chinese Whore.
Alex Trebek: No.
John Travolta: 'Chinese Whore' doesn't rhyme with dog.
Alex Trebek: Yes, that's why it was a wrong answer.
Michael Keaton: I'm Batman.
