I , like some others were saying, love to watch intellectual stuff every now and then. I have the Planet Eatch (Discovery Channel) DVD set, and man it is great stoned or not. It is amazing some of the stuff you see on that show. But thats just me, I love nature and all the weird and interesting animals. Tell me if you were stoned to the bone, and watched a clip and salamanders that live high up in the cold mountain streams that grow to BE 7-8 FEET LONG and live for 80 YEARS, you wouldnt be flat out amazed by that. Like I said thats just me though.
When it comes to actual shows rather than documentary type shows, I love Entourage and Weeds. I also like the new show East Bound and Down (main character is 'Red' from Pineapple Express)on HBO. It is hilarious. Really, HBO and ShoTime make some really great shows with really great characters that you get connected to. Some other great ShoTime shows are Californication and United States of Tara. Dexter (which plays on cable now, but the new episodes air on ShoTime) is pretty good when you are stoned, if you like the dark, gruesome, Saw-esque, murder shows. I really suggest anyone that can afford it, get HBO and/or ShoTime, and if you cant (understandable as ridiculously priced cable is these days), download some of the shows on these shows from Vuze or something. You shouldnt be disappointed.
When I am stupid high, and just cant handle anything intelligent at all ha, I like to watch Family Guy. But to be honest, it makes me feel even dumber after I watch it, so I try not to watch it too often.
