From the Daily News:

Tina Fey dissed archfoe Aaron Sorkin Sunday night at the Writers Guild Awards. The “30 Rock” star competes with Sorkin’s “Studio 60″: Both take place behind the scenes at a show like “Saturday Night Live,” where Fey was head writer. Wiggling around the Hudson Theatre stage in a party frock with plunging decolletage, Fey told the crowd, “I hear Aaron Sorkin is in Los Angeles wearing the same dress – but longer, and not funny.”
