Some fanfic help?

My best friend (male, oh, the surprise!) is a total Batman nut who of course, loves Poison Ivy and Harley Quinn.
Does anyone here have femslash? Or het would be okay, too, I guess, if it's dirty, lol. But any hot femslash would make him the happiest nerd in the world. I would be ever so grateful.
