Surely that was done as a practical joke. Those guys were slick, funny shit. Ha ha...they had to show up, be real quiet; tell them some fake name in a girly voice, then go through everything backstage without the other women noticing them...which would have been the hardest part because the other girls are gonna be checking out their competition...I bet they knew but just didn't know what to do...one part taken aback that someone would actually do that, and the other part embarassed that those guys showed features that weren't that different in actuality from their own. Oh brother. Those guys have nerves of steel doing that shit. ha ha
