Felicity Huffman was on Letterman last night when the subject of her husband, William H. Macy, replacing the sushi-poisoned Jeremy Piven in the play Speed-the-Plow play came up. Felicity wasn't exactly kind to the Piv.

She mentioned that Macy used to babysit for Jeremy when he was but a rugrat. She then sardonically added, "In some ways you could say he's still babysitting him." Zing! Then, when Letterman smirkingly brought up the whole mercury-poisoning-by-tuna thing, Felicity scoffed a bit and seemed mighty incredulous. So now it's OK just to rag on this dude's lame story on national television. Even if you're an image-concerned fellow celebrity. It's almost kind of sad.
