Leftard Douglas Kenney, the original screenwriter behind "Caddyshack" was the founder of National Lampoon. It made him rich.
So Doug exits Harvard with money sticking out of his hole, but wants to be one of the cool kids. Enter Ramis and Doyle-Murray.
Caddyshack is eventually a success but Doug is bummed because they hollowed out the caddy story to appropriately accommodate Dangerfield/Chase/Murray/gopher, and the initial reviews were mixed.
Yet one scene made it into the movie : "In the background of the Bushwood Club dinner party scene, Kenney is visible chopping out a line of cocaine for the female guest next to him. And he is seen dancing with her."
Anyway he flips out at the premiere, so Chevy took him to Kauai, then left. They found Doug's body underneath Hanapepe Lookout.
Harold Ramis was a vastly underrated writer/director a pretty good comedic actor.
