As Steven Wright once said about the Indy 500 - "If they left earlier, they wouldn't have to drive so fast".

Anyway, I believe that Nascar was invented for people who weren't bored to death by televised golf. Then, in an attempt to prove that neither were the most boring things you could watch, they started televising poker. It's so boring, even the commentator's can't think of anything to say. NBC broadcasts it at 2am, which is a good time, as it's a sure cure for insomnia.
