I'd have them over... serve everyone a few rounds of beer, pull out your ipod/phone with the downloaded "stripper song' and hit play. Playfully dance around the room and give them a few teases before pulling out the one eyed monster. This should make everyone giggle, satisfy their curiosities and convince them the stories are true without creating an awkward situation. Once you're exposed persuade them participate on the 2nd verse. If it leads to anything else... fine, if not, mission accomplished and no harm done.
