You might have heard that Mensa, the organization for people with very high IQs, has assembled a list of the Smartest TV Shows of All Time. Frasier makes the list at number 8 (aided, no doubt, by the performance of David Hyde Pierce as natty Niles) and four shows known for occasionally tackling gay themes - The West Wing, Boston Legal, Mad About You and All in the Family - are also included.

The full list:

1. M*A*S*H
2. Cosmos with Carl Sagan
3. CSI
4. House
5. West Wing
6. Boston Legal
7. All in the Family
8. Frasier
9. Mad About You
10. Jeopardy

As always with a list like this, a number of omissions come to mind, ones that makes the inclusion of Boston Legal and Mad About You seem even odder. Seeing Mensa chairman Jim Wardell explain the choices doesn't help things, since there doesn't seem to be on over-arching rationale; CSI and House are considered smart for the way they use science in their stories while Frasier and M*A*S*H are praised for their characters and dialouge.

While a list of this always inspires people to think of their favorite deserving shows (I always go with Wonderfalls, myself) there are a couple general omissions that I find interesting. All of these ten shows originally aired on broadcast television, so critical darling cable networks like HBO and fx are not represented.

Animated and science fiction series don't make the cut, nor do any gritty, emotionally exhausting dramas like Homicide or Six Feet Under. One could almost say that Mensa picked shows that were intellectually challenging but not too intellectually challenging.

The most glaring omission is probably The Simpsons, a show that playfully challenged its audience's attention to detail almost constantly. Does the fact that Lisa Simpson is a high-ranking member of Mensa Springfield mean nothing?

But there are plenty of other gay-inclusive TV shows that could fit on the list. Earlier, I mentioned Homicide (which gave us an unflinchingly realistic look at police work and characters who developed over time, including Kyle Secor's Det. Bayliss becoming comfortable with his bisexuality), Six Feet Under and Wonderfalls, and would also think Oz and The Wire would be deserviing nominations.
