I loooooove my Forum Novelties Chatter Choppers - Chatter Teeth! They are so much fun and always make me smile. I'm that weirdo who loves to put them in without warning and terrify people, haha. Plus the reactions when they start moving are just too funny! Pretty sure everyone around me thinks I'm a kid again (it's probably not helped by the fact that I still watch cartoons!) It's also great for party games as it adds an extra level of challenge since you can't really talk with them in. Oh, and forget about looking normal if you wear these out--people stop you everywhere to ask where you got 'em from.
Speaking of which, this particular set is excellent quality for what it does: 1 pc per package with churning teeth action that never fails or gets stuck like some cheaper sets do. They last pretty long too; mine have held up through plenty of events already and don't show any signs of giving up anytime soon. All in all, super happy with my Forum Novelties Chatter Choppers--definitely worth every penny!
