How does the Riddler ever find henchmen? I mean, c'mon!

[Bucky]

Where do you even find people that stupid? He must be hiring junkies. What other professional criminal would put up with his shit? I mean, he's like, "Thanks for getting the floor plan for the First National Bank of Gotham, Smitty. Now we can go rob that place, right after I send this desperately obvious clue to Batman in the form of a Hallmark card, care of the fuckin' police commissioner."

In fact, why do the police even need Batman for this ass clown? His suck ass riddles are shit like,

--Knock, knock.
--Who's there?
--The jewelry store at the corner of 14th Street and Hudson Boulevard that I'm going to rob Tuesday night.
--The jewelry store at the corner of 14th Street and Hudson Boulevard that I'm going to rob Tuesday night who?"

The cops can't even cover that one? Get real. He's probably got so many crooks tossed into prison by now with all his moronic self-defeating clues that he wouldn't last very long in the pen, anyway. Why isn't this clown dead?
