Sarah Michelle Gellar is newish to Twitter, having only joined last October, but she sure knows how to get us to follow her: Last week SMG posted a photo of herself and former Buffy the Vampire Slayer costars Seth Green and Michelle Trachtenberg from the set of her new series, The Crazy Ones.

Could there be a Buffy reunion in the works for Crazy Ones? Sweeps are in May, after all.
