WTFWJD?

I saw this on a t-shirt yesterday, and I thought it was hilarious. I am well aware that this parody has been probably been floating around for ages and I have just now caught on, but I don't care. I just love it. WTFWJD?
What I find most amusing is this: as a blaspheming atheist, "What Would Jesus Do?" has never meant much to me. But now that someone has made this sacrilegious joke about the WWJD thing, that joke might actually have the effect on me that the original acronym is meant to have on Christian type people. It's like this - in a difficult situation, you're supposed to think, "What would Jesus do?" and ultimately take the most charitable action. So now, in a difficult situation, perhaps I will have the thought "What the fuck would Jesus do?" and I will chuckle inwardly, cheer up a bit, and then maybe, be in a better mood to deal charitably with the confrontation.
