Love the puzzle pieces in the Easter eggs idea and will be stealing it!
Growing up we played a game called "Dictionary." We would pass around a big dictionary and find a word that no one knew the definition. The person with the dictionary would write the real definition and everyone else would write made up definitions. Then all the definitions were read out loud and we'd vote for the best choice. You'd get points if people believed your definition and also style points for the funniest one.
My favorite was horripilation. The true definition is goosebumps but someone made up "the horrible ripping off of lips."
