I got Sheldon this silly little plush cheeseburger today at Petsmart because it was on clearance for $2 and my youngest son, Seth, thought the toy was hilarious. Sheldon has not put it down all day. It's half the size of him, easily, and he has been carrying it around and shaking it for nearly ten hours (between naps and meals).
From now on, I'm not buying anymore fancy pricey toys. I'm going for the cheap ones
