Wedding Crasher's Rules.

Rules of Wedding Crashing (there's a lot, apparently):

Rule #40: Dance with old folks and the kids. The girls will think you're "sweet."

Rule #55: If pressed, tell people you're related to Uncle John. Everyone has an Uncle John.

Rule #109: Always carry an assortment of place cards to match any wedding design.
