I originally bought Yellies for my brother's kids (because I'm such an aunt) but ended up using some of them as prizes in the Toastmasters Achievement Contest. You flip a switch, put them on a hard surface and yell at them, they move. I can't say why this always pisses me off. Other adults found them just as funny as I did, and it's definitely better than giving away another batch of cheap plastic trophies. The yellow candies were a huge hit and I buy a few for every last minute Christmas present for kids and adults.
