Decorate! Make the birthday boy or girl feel special - and young at heart - by hanging long pieces of string across various walls and clothes-pinning all the embarrassing childhood photos of him or her you can find. Create party-favor cupcakes or tee shirts emblazoned with the choicest childhood image of them all.
Dance! Before the party, create a meaningful playlist for your MP3 player: all the guest of honor's favorite music, plus songs from the year of their birth.
