I'll admit that it wasn't the best episode that I've ever seen, but I tended to agree with the idea that NASCAR is for the poor and stupid. It is quite pointless just going round and round very fast.
Some of the Vagisil references were very funny, as was the use of the Valvoline "V" on the their sponsorship.
I've watched the episode three times now and it's more than OK, but it won't be remembered as a classic.
