Yes, and it wasn't too long ago either. But now, my son Josh Miller has sold a FOURTH t-shirt slogan to threadless.com, and this one is probably his best yet! http://www.threadless.com/product/2323/Apathy_Our_Country_s_Leading_Cause_of_Whatever
The only problem is that a quick look at his many many other slogans submitted to threadless demonstrate that most of those are just as clever or funny or imaginatively ironic and they should also be printed. Too bad they can only introduce a couple new ones per week. And it's not like I'm just a proud Dad or anything (is it?); his stuff is really good! Go buy a shirt!
