Deviant art user BillWalko drew this awesome mash-up of the Mad Men (and Women) of Arkham Asylum.

The Riddler’s focus group questions are maddening. Two-Face is obsessed with 2-for-1 offers. Poison Ivy has founded a go-green movement. And the Joker keeps running out of pencils. But at the end of a rough day, Harley Quinn is ready with a drink that will knock you out (umm, literally)!
