Life's Deep Questions: WHO 5HAT?

MetroRod Drain Services is the British version Roto-Rooter in the United States. If you have a clogged drain or toilet overflowing with poop, they're there for you!

And the good people at MetroRod also have a sense of humor; witness this van's WHO 5HAT license plate.

That's mean!

If you're ever in Alabama, keep an eye out for the cannibal in the BMW. This horrible, horrible license plate raises a few questions:

1.) How could the DMV have allowed "I8ABABY" in the first place?
2.) Why is the driver telling us he ate a baby? Does he think we'll be impressed?
3.) This is a little off-topic, but what kind of gas mileage does that car get?

Addition: A very grumpy commenter who may or may not own this car has informed me that the phrase "I ate a baby" is from the Austin Powers' movies. (Gee, that changes everything!)
