In this episode go to the last skit before the musical guest sings, which is the "Spice Boys" skit. At one part, Sweaty Spice is putting some of Hairy Spice's hair into a pillow, if you pay attention to the pillow you will cleary see a crew member with a hat switching the pillow to a square foam piece in a pillow case. What I don't get about this slip up is why did they changed the prop? But it's still a really great skit.
