I've got two that have survived relatively intact: one that I won in French class back in high school which has "Hello" in French, German, and Spanish on one side, with "Goodbye" also in three languages on the reverse. The other is a "Newberry College Quiz Bowl" t-shirt which I acquired as a gimmie while part of the high school "academic team"
and I think I'm the only person in history to actually wear it.
I also have a nice t-shirt of the 12-inch cover for LWTUA which I rarely wear, in order to keep in it nice-even-though-it's-been-worn state.
