re: Who are your favorite reoccurring Seinfeld characters?

The iconic, mysterious, friend of only Kramer (and as told to us by Kramer); famed seller of Rat Hats, long-term couch guest of Kramer, a man who survived Rabies, worked in a Condom factory, was once in a mental institution where electroshock therapy had no effect on him, and the co-inventor of the ball and paddle toy (he came up with the idea of the rubber-band so the ball wouldn't fly away.)

The man, the myth, the legend...Bob Sacamano.
