MY party idea is for 'NSYNC Fans. Start by sending out the invitations. For the invitations cut out circles the size of CD's and decorate them and put the information you need on them.    For the area that your throwing the 'NSYNC PARTY decorate with home made posters honoring the group. Make banners or buy them. You can buy 'NSYNC PARTY supplies at party stores to decorate your 'NSYNC Party. Have each fan bring a poster they made. The poster could even be a card for the special birthday person. Play any and all 'NSYNC MUSIC. You could even display the CD's .Play 'NSYNC VIDEO'S.    The food serve pizza but don't add toppings 'NSYNC wouldn't approve of. Treat's include 'NSYNC's favorite candies such as SPREE'S. For drinks serve the guys favorite's and the Birthday person's. Buy an 'NSYNC Cake these range in sizes and pictures.    For games play basketball , hackey, play 'NSYNC TRIVIA  and give out small prizes like 'NSYNC Stickers, 'NSYNC PENS, OR 'NSYNC KEYCHAINS. You could have them play part of an 'NSYNC song and then turn it off, and finish the lyric. If they correctly get the lyric than they win a prize. By the time this party's done they won't want to be saying bye,bye, bye.
