Every college comedy needs its disapproving dean or, in the case of Tina Fey’s untitled multicam, its constantly exasperated president of a women’s university. Margaret Cho has joined the cast of the Fey-produced Fox sitcom as a series regular, portraying Cabot College president Laura Thibault. Cho’s character is described as a “divisive figure on campus,†having allowed male freshman to matriculate only to be “often irritated†by their shenanigans. Considering Cho snagged an Emmy nom for her guest appearance as Kim Jong-il on 30 Rock, it’s not surprising that she found a role on a Tina Fey project. Maybe Kim Jong-un could stop by Cabot and get an honorary degree. Hey, we don’t know the reality of this show yet. It could be that ridiculous.
