I stop at Goodwill, etc. a few times a year and cruise the black t-shirt racks for old wrestling shirts. I scored a Wolfpac one (with a wolf on it!) and a Goldberg one a couple weeks ago. Made my day, even though I only wear them while walking the dog and amuse my buddies. Plus the wife of one of my friends is a big rummage sale person and has strict directions to purchase any that she comes across in her travels.
