I saw this two on HBO in 1992. Remember HBO played that Sam Kinison Comedy Special in 1991. I remember this was when Infocommercials starting getting popular. Kinison did a skit on it. He talked how he was watching TV at 3 in the mourning. This guy comes on TV and said he found the greatest discovery. Sam goes, i'm thinking they found the cure to Cancer, or cure to make paralzed people walk. Sam then goes, it turns out the great discovery was how to Wash A Fuckin Car. Next Week, the great discovery will be how to Mow the lawn.
It went something like that. But it was so funny.
