I thought you might like this "thing." My brother bought it at a yard sale about 15 years ago. He gave it to me. I wondered if you (or your readers) might know anything about it. It features an interchangeable rubber face. That's about all I know about it.
Here's what I know about it: aaaiiiyeeeee! That is one deliciously terrifying thing, made all the more disturbing by the fact that it's playing "When the Saints Go Marching In" as the background music. I have no idea what it is, but it's a winner. Save it to perch at the end of your child's crib.
(The video is safe for work, but perhaps not safe for your soul.)
