We've got this little fella in our fridge (he's a Fridgeezoo Fridge Pet - get 'em at firebox). When the light comes on, he says stuff like "hello" and "shut the door". I did wonder if we'd find him irritating, but actually, he's really quite cute. He just chats away when the door's open, and goes quiet when you close the door again. He's sort of like a kitchen pal that's keeping an eye on things while you're not there :-)
