Toby pointed me at http://www.shipoffools.com/Features/2005/laugh_judgment_results.html, where a bunch of quite devout (and apparently quite humourless) christian types discuss and vote on a bunch of offensive religious jokes, attempting to determine the funniest and the most offensive. Some of them are quite good - and then you read the comments, and they're even funnier. Not funny in a "what a clever and witty person" kind of way, but in a "what the hell is wrong with you people" kind of way.
Note that some of the 'most offensive' jokes are really quite offensive. If you're in any way lacking in a dark sense of humour, you might want to skip them.
