Conjoined Twins.

I was watching a show on the Learning Channel and it was about conjoined twins. Specifically, these twins. Now, I'll be honest, my first response to seeing this was to laugh and think, what a freak! (You did too, don't lie) But really, they're quite remarkable. They each control one arm and one leg, and they do things like sports, piano, and typing on the computer. How can you type with 2 hands when you don't know what the other hand is doing? Even walking would require co-ordinating your steps with someone else who you don't control. It's crazy! They drive as well! Anyways, I just thought it was interesting that there's a 2 headed girl out there. I also thought that it would be interesting if that conjoined twin had a kid (with one head) but didn't let the kid out into the world until they were about 15, so for 15 years the one headed kid would be thinking that they were the different ones. Imagine the look on their face when they see all the other one headed people out there! Classic.
