I say we put people to a tickle test. When they least expect it, tickle them to see if they do an "outside, in front of their 'friends' laugh," during the tickle. If they do, cool. If not, fine them $20 bucks and make them promise to never do it again on a youtube video.
Guys do it, too. I've watched a Super Bowl game or two, but the Budweiser frogs, E Trade babies, Betty White in the Snickers commercial or whatever are funny, but not THAT funny.
