It might reference a cult classic moment, but does anyone really want Batman in Bermuda shorts? In an infamous scene from the 1960s Adam West television series (the 1967 episode "Surf's Up! Joker's Under!"), Batman and the Joker went up against each other in a surfing competition. The Joker planned to become the king of surfing, hoping that the fame it would bring would give him control over the hearts and minds of the people of Gotham City. He captureed top surfer Skip Parker, then uses his "surfing experience and ability transferometer" to transfer the needed skills and stamina from Skip to himself. When all the other contestants drop out of the upcoming surfing contest at Gotham Point, Batman steps up to challenge the Joker's supremacy. What follows is a ridiculous sequence in which the pair surf (utilising atrocious special effects) and the series jumps the shark in the most hideous and heinous of ways. Having a toy to commemorate it, complete with surf board, really isn't what the world needs.
