Anyone who follows the wacky downtown crowd knows that Strangers With Candy genius-slash-cupcake maker Amy Sedaris and actor Justin Theroux (Broken English) are, like, total munchie buds. So last Friday night, it wasn't a surprise to see them both: We were at the opening for the eerily named "Sometimes Comes Mother, Sometimes Comes Wolf," an Adidas-sponsored installation by Theroux and designer Douglas Little. Open daily through February 9, the installation, which sits on Broome Street between Ludlow and Essex, is a big, iridescent modern blue box on the outside and a Victorian apartment on the inside, full of creepy curiosities, many of them from Theroux's own apartment, like a terrifying pile of ventriloquist's dummies, various stuffed bats, and, poignantly dumped on a velvet pillow, the cremated remains of Pooma, Theroux's beloved pit bull, who died a few weeks ago.

In return, she said, Theroux had given her "a makeup kit for dead people." Not to mention ... "Hey Justin," she called the actor. "Remember that odd thing you gave me? Something to do with a woman's — it was really nasty." Theroux, who said that Ben Stiller was directing a movie he'd written called Tropic Thunder, chimed in: "It was a really old douche bag," he said. "Honestly. Metal implements and everything. I think it even had a tube of cream in it, didn't it? Used cream." We asked Sedaris where she kept it. "In my bathroom in a cabinet at the bottom," she said. What, she didn't display it proudly? Even Sedaris, it seemed, wasn't that weird. She assured us: "I only pull it out for show and tell."—Tim Murphy
