I don't have any serious problems with the play on words, but I agree with other posters that it's old and tired, and likely to not be amusing to anyone beyond adolescent boys. Speaking of children, I would ask Mr. Cook what his kids read out loud and ask about when they see any of the several large billboards around tow advertising adult toy stores. I have a much bigger problem with those billboards than I do with a kitschy burger joint with an old joke for a name.
