I know its hard to recommend programming to other people, because if its dated, its a hassle. So if you always wanted to know why MST3K (Mystery Science Theater 3000) had so many fans, here is a semi-secret never-ending stream of it.
I am also a big fan of their modern efforts via RIFFTRAX.com where they make fun on first run movies. And Although I just watched IRONMAN, their take on the original HALLOWEEN was hilarious.
And not to be missed, Season 8 of "Happy Family Plan" was lovingly posted on YouTube this summer (just do a search). Its a Japanese game show where the head of household has one week to master a difficult task and perform it without errors in front of a life audience (no pressure) for about $30k in prizes.
