I've started a meager collection of cards featuring player nicknames, which pretty much just consists of Topps releases for Tim "Rock" Raines and David "Boomer" Wells. But I'm sure with a little effort I could expand the collection.
The Pirates have had their fair share of great nicknames, but how many teams can boast a nicknamed tandem? Add in a pair of HoF plaques, and you have perhaps the most famous nicknamed duo in history.
Double your poison, double your fun.
