Right there with you.
The DCU also has Joker action figures. Without even getting into the issue that there are people out there who had the terrifying and morally bankrupt idea of selling Joker action figures, what kind of a parent would buy their kid Joker toys? 'I'm so sorry, sweetie, the Charles Manson doll you wanted had sold out, they only had the Joker'?
It's funny for the reader, but clearly it points that people in the DCU do not operate with our Earth logic.
