Pulled from the pages of FARK: MENSA Announces 10 Smartest Shows.
There is only one show on that list I agree with and that is number 10.
Where is Mythbusters? And M*A*S*H? CSI? Give me a break.
Check the TV Squad link on the page for some other suggestions, especially in the comment section. I was happy to see someone mention Win Ben Stein's Money.
