Norm Macdonald, who starred on Saturday Night Live from 1993 to 1998, returned to help out with the writing of the SNL 40 special that aired February 15, 2015.

Here are some of the highlights of his story, which ran for over 100 tweets. The "Higgins" of the story is Saturday Night Live writer Steve Higgins, while the "Lori Jo" is Lori Jo Hoekstra, a producer who has worked with Macdonald on SNL and several of his projects since leaving the show. When he refers to asking Martin Short for permission to "steal" Celebrity Jeopardy, he means that Short was a cast member on the influential sketch comedy show SCTV, where the idea originated (as Macdonald explains).

The story involves Eddie Murphy, Bill Cosby, and what sounds like an absolutely insane writing process. Read the unabridged version at Macdonald's Twitter feed, and check out the final skit here.
