Brothers Nick and Travis Peterson have collaborated to make the ultimate in gag novelty greeting cards.

Quite possibly the GREATEST novelty birthday gag EVER created!  If not the greatest, then possibly the most hand's down obnoxious.  Ever see those birthday greeting cards that play a song?  Those cards are lame.  This greeting card has been specially designed to play a birthday greeting, non-stop, FOREVER.  Well, it seems like forever...around 3 three hours.  Yes, once the card is opened, the song doesn't stop.  The only way to stop the song is to wait for the battery to die or to physically destroy the card.  

"Basically we just wanted to make something to make our friends really angry, so we can laugh at them."- Nick and Travis Peterson, creators.
