....Carnac!
Yes, Carnac, the psychic boy!
For those who don't know what we're talking about:
A couple months ago, he predicted that my wife would be in a car accident. She dropped him off at school and he was crying and having a fit (which he never does), and he told her not to leave him because it was dangerous. Less than a half a mile later, some kid ran into her at 40mph. She was okay thankfully.
I picked my son up from school later that day and asked what he meant when he told his mommy that it was dangerous. He said that it was dangerous because a car was going to crash into the back of her car, which is exactly what happened.
So... that's why Mark calls him Carnac.
