Discovery Channel show tonight: "I Am My Own Twin"

Buddy says: "There's a program on Discovery Health TV Channel tonight about when (human) embryos fuse together during pregnancy. The title is I Am My Own Twin."

Babies are being born split right down the middle, half black and half white, a testicle on one side and a vagina on the other. Explore the extraordinary medical phenomena that causes two different babies to fuse together in the womb.
