Jack Perry’s other famous family

So when he got his start, Jack Perry’s opponents used to get heat by talking trash about Perry’s famous father.  But why does nobody ever talk about his even more famous uncle?  As everyone knows, Luke Perry’s half brother is none other than Krusty the Clown making Jack Krusty’s nephew! Are men like Chris Jericho just afraid of the man who (as far as we know) invented the flapping dickey?   You would figure Tony Khan could make billions by signing the family of his uncle’s most famous enemy Sideshow Bob and booking a blood feud.  Or is Krusty just too big to appear on a wrestling show?
