Pay particular attention to tonight's episode of The Crazy Ones (8 p.m., CBS/Ch. 2). The plot involves Sydney (Sarah Michelle Gellar) and a bunch of cats - and Gellar is hugely allergic to cats.
If you pay close attention, you won't actually see Gellar in the same frame with any of the kitties. You might see a double, but not Gellar.
