To come up with some very tacky T-shirt slogans:

... "Goat - it isn't just for breakfast any more." [Both English and Arabic versions]

"The road to Paradise begins with me." [Mostly Arabic versions but some in English. Some show sniper scope cross-hairs]

"Guns don't kill people. I kill people." [Both Arabic and English versions]...

I've seen a few of these available here in the states, but I do agree with Jason that if this really is a problem it's probably a good thing someone's taking steps. It's one thing to offend some soft-headed liberal arts & crafts sophomore at an anti-war rally in Berkeley. It's quite another to offend an Arab holding an AK-47.
