10% off on AnnoyingTeddy the Prank Happy Birthday Singing Teddy Bear at https://www.annoyingteddy.com/ for coupon code "BDAYPRANK"
Originally featured and funded on Kickstarter.com - This amazing diabolical teddy bear sings Happy Birthday to help someone celebrate their big day, except once started the song does not stop and cannot be turned off (pressing the button again does nothing and the batteries/electronics are sewn inside and not accessible). The once cute, high-pitch Happy Birthday song quickly becomes increasingly annoying as minutes and then hours go by!
