Wouldn't this give you a nightmare?

Nope. Google images of "Fetus in fetu" if you dare

That, will scare you.

Dude why did you have to bring up bad memories? I watched a video in my AP Bio class last year about a boy who had a fetus inside of him... They removed it and holy pomegranate it was scary and sick... I then had to eat lunch. *shudders*

EDIT~ I think the picture is kinda cool/cute. He looks like he has shades in the first pic.
