Possibly Batman's Most Half-Assed Disguise

Okay, I'm not as sure about this one as I was about the obscurity of that Superman power,  but I like using the superlatives.

Still, though: purple hat and cloak over top of his regular Bat-duds? Travis Morgan goatee? If this isn't the most half-assed of the Dark Knight's disguises then it's as least in the top five.
