One of the great things about Batman and his magical universal funniness

...is that even in Smallville fic where he makes no appearance he is frequently the funniest joke:

"Do I want to know how?"

"Batman's a Yenta."

     from The Fantasy by Marag, an enjoyable and somewhat silly schmoopy wish-fulfillment clichéfic in which Lex hires a Clark-alike hooker

Batman's. a. yenta. XD Perhaps this should be defined in the Batman Humour Law, similar to Dave Barry's ( maxim about weasels. Go on, you want to know! )
