Who knew those recordable greeting cards were good for anything beyond being incredibly annoying? No, there’s no way Courtney (Rose McGowan) could have realized Julie (Rebecca Gayheart) accidently recorded her murder confession while messing around with their late BFF’s birthday card, but if we learn anything from murder movies, it’s that you just don’t ever announce that you’re the killer, especially as proudly as Courtney opts to. The bright side of this recording blunder? Hearing "I killed Liz. I killed the teen dream. Deal with it!" play on repeat at the prom. It really is the ultimate payback.
