The item description is a reference to the movie Major League, in which a Cuban character named Pedro Cerrano appropriates another character's golf club covers and places them on his baseball bats. As the other character tries weakly to object, the imposing Cerrano says, "Hats for bats, keep bats warm. Gracias."
The item image also resembles a hat made of a live bat created by one of the characters in the movie The Nightmare before Christmas.
