Quite often these shows have security guards whose job is to keep hopeful male visitors from hassling the models; they don't always wear rentacop outfits, but they can usually be spotted by their beefy build and watchful demeanour. Having said that, if you manage to get past the guards, a line that you could use is this: Ask her if she likes poultry. If she says "yes", whip your penis out and say "suck on this, because it's foul". Works every time.
