I was off three days last week due to a cold and watched Californication all 6 seasons. That is friggen funny. http://stream-tv.me/watch-californication-online/
it's not just the cliffhangers. Usually every show has a few slow moments in the middle of the show that may put you to sleep.24 hours is probably too long for me for any show...
but to go along with the question, I'd say Season 1 of Prision break.,.. just cliff hanger after cliff hanger which would keep me at the point where I have to know what happens next... but only season 1.
