Maybe the poster has a time machine and was visiting a Goodwill in the year 2027. In the big cardboard barrel, jammed in among miscellaneous massive-headed golf clubs, are a bunch of ground down Babolats. The donators of said racquets are in the market for the new nanobionic elbow implants. Plus, it more fun to play "virtual tennis" on any holographic video game station with virtual friends off the ultrainternet.
Hahaha! Yes, busted! That's exactly what happened! Needless to say I was pretty surprised to find them.
