tomorrow's [South Park] episode, the first of the 10th season, will feature "the triumphant homecoming of school chef, Jerome McElroy," Comedy Central announced. (Yes, that is Chef's name, as diligent fans know.) Stan, Kenny, Kyle and Cartman are happy to have him back, but "they notice that something about Chef seems different," according to the statement. The episode, titled "The Return of Chef!," will be on at 10 p.m. Eastern time. A spokesman for Comedy Central said there was no word on who would do Chef's voice.It's already the fastest-responding show around, but this would seem to set a record even for them.
