They've been doing this every week for a couple months... The first girl (Sabrina), in particular, has taken much better hits than that one, actually. (She also has a tendency to "dodge" the hits lately, unfortunately.)
This was actually a pretty disappointing week. Take that amazing pie hit, multiply it by 8... And that's what happened to the guys.
This show is so much better now that they've got them sitting down when they get pied. I don't know why (maybe it's a better angle), but it really enhances it for some reason.
