I've Seen It All Now: Air Guitar Strings
Air Guitar Strings cost $3 plus shipping and are an empty package that reads "Air Guitar Strings". Very clever. if you're thinking about buying them, here's an idea: why don't you give me half the money you were gonna pay, then we'll go out back, I'll kick you in the nuts, and we'll call it a day?
