Sledge Hammer, Sports Night,
I'm pretty sure Dream On went more than two seasons.
I think Aeon Flux Techinally had 3 seasons.
Get life. Out of this world.
Fawlty Towers. (seems longer since the show filled a one hour slot and British TV series run differently, but officialy the show was only two seasons.)
Actually, The Good Life only had two seasons too!
Crap, you said pick a favorite!
I pick Sports Night. It was the ONLY show I ever felt strongly enough to write an email and request more episodes. Everything else I just let die.
I have also heard the rumors of starting up Futurama, Family Guy, and Sports Night again. When I see new episodes actually playing, I'll believe it.
The thread-friendly GagHalfrunt was referring to
www.tvtome.com.
They actually go over every shows season in order.
And when I say every, I mean many times more thorough then
www.imdb.com.
Check it out, just in case anandtechers really can count higher than two.
