One of the biggest challenges of speaking at a party for a milestone anniversary is that the audience may span as many as four generations. A clever way to please elders and jaded teens alike is to make the toast interactive. At their golden wedding anniversary celebration, one woman had her parents sit back-to-back onstage and answer Newlywed Game-style questions ("Who's more likely to lose their luggage on vacation?") that were read aloud by guests. Everyone talked about the toast for years afterward.
