This show is a pile of shit.
I've made a diagram of how the show seems to work.

Some people argue that because of Christopher walken and other amusing people, that the show has on occasion been funny.
However I inputed this data into my computer and ran it against the 300 years "SNL"* has been on the air, I came to this conclusion;
Using time as a constant, and the variable of actually laughing or smiling, the uncertainty principle provides the missing equation. "It is utterly impossible for an organism or entity to live or exist every saturday night for three hundred years and not accidentally or coincidently create some kind of humor."*
I will be publishing my findings in The American Journal Of Mass Delusion (AJMD) at the end of this fiscal year.
