My buddy and I used to watch this when it was first on HBO 100 years ago. A lot of the stuff they did then WAS cutting edge, but it looks old and blah now. The woman on the game show with her boobs hanging out? That was just unbelievable back in the 70's. Who ever saw boobs on TV before that (National Geographic specials excluded)? The part with text scrolling by down the screen mocks some of the early "channels" that cable companies had up. We got cable in 1973 and I remember watching the news wire channel where someone was typing the news as it came in and you read along. Sometimes nothing would happen for 10 minutes and I'd sit there waiting for the next story (how pathetic, huh?) Anyway, this will only be "hilarious" once you watch it 20 times and memorize the dialog. THEN some of it is truly inspired. My friends and I used to recite the cursing construction workers "Hey I got a f*ckin' lug nut in my f*ckin' work boot" over and over.
Don't expect to die laughing the first time. But maybe by the 4th or 5th you'll start to get into it.
By the way, I bought this on VHS from the National Lampoon site a couple years back, so it IS out there if you look.
