I used to be a big fan of Sesame Street, like most young children. I had a few Sesame Street toys. One of them was a stuffed Elmo doll that sang the alphabet when you squeezed its tummy.
One day when I was playing with that Elmo doll, I noticed that it had a rip in its back. I opened it up, and I pulled out the device that the sound came out of. It had a big button on it, so I pressed it. Sure enough, it sang the alphabet in Elmo's voice.
To make a long story short, I was distraught that it wasn't really Elmo that was singing.
