This Portlandia Episode, sorry, Old Navy spot, features Fred Armisen and Carrie Brownstein playing themselves-- and also themselves in drag! Kinda like Eddie Murphy in The Nutty Professor, except they mention Old Navy six times. Dabitch pointed out the real underlying message of this spot: Horrible people go to Old Navy.

See also the short edit and the skit where they have to sit at the kids table:
