I've noticed at the end of the show, a blurb says "Some traders will receive duplicate prizes for zonks" or something like that. Translation please.

I'll try

Say you win...An Elephant

After the show, technically, you could take the elephant, but usually, (and I may be wrong over this exactly), you could get a giant stuffed elephant and the cash value OF the live elephant (Barring you taking the actualy elephant (And someone REALLY DID want to keep their animal Zonk once)))

Actually, that was on The Price is Right from the 1960s. A man won an elephant and refused the money of the elephant. The law says that he gets what he was told, and they got him an elephant. This was the premise of a Simpsons episode as well.
