In a stunningly moronic discussion about cloning on the Bill O’Reilly show in 2007, GOP candidate Christine O’Donnell warned of the dangers of mice with fully functioning human brains.

O’DONNELL: Bill, if we — if we approach this complicated bioethic issue with our heads in the sand, the other end is in the air.

O’REILLY: My head isn’t in the sand, Christine. I have the biggest head in the world. There isn’t enough sand on the beach in Hawaii for my head to be in there.

O’DONNELL: My point is, we’re approaching this issue with the other end in the air.

O’REILLY: No, no, no. Hold it.

O’DONNELL: By their own admission…

O’REILLY: No.

O’DONNELL: … these groups admitted that the report that said, “Hey, yay, we cloned a monkey. Now we’re using this to start cloning humans.” We have to keep…

O’REILLY: Let them admit anything they want. But they won’t do that here in the United States unless all craziness is going on.

O’DONNELL: They are — they are doing that here in the United States. American scientific companies are cross-breeding humans and animals and coming up with mice with fully functioning human brains. So they’re already into this experiment.
