I made a 5-string banjo out of a bedpan (a PANJO). Cathy Fink owns it now and I've a photo of Pete Seeger picking it in Cathy's kitchen.

Also, for years I did shows in and around Chicago mostly with a dulcimer made from a Star Wars lunchbox. It looked more like a banjo --the box with a neck--but it only had 3 strings and was fretted with staples from a regular stapler that were spaced like a mountain dulcimer.
