This isn't actually one of mine, but I thought it was great. When my mother was a girl, she had (and still does) the ability to shoot a tiny stream of spit between her teeth. Apparently my grandfather was not amused since he told her that the "acid" in her saliva would melt holes in the upholstry of their car.
