Occam's Razor (also written as Ockham's razor from William of Ockham (c. 1287 – 1347), and in Latin lex parsimoniae) is a principle of parsimony, economy, or succinctness used in problem-solving. It states that among competing hypotheses, the hypothesis with the fewest assumptions should be selected i.e. less is more e.g. The Mummies.

I was walking with a friend of mine
Doing nothing just a passin' time
Got a notion that'll do you good
Eat a pizza down in Hollywood
In the alley behind the laundromat
Stab the motherfvcker in the back!

Marlon Brando & Jimmy Dean
Stupid clowns didn't mean a thing
I don't really care if he was gay,
was he cuter than Doris Day
With his shoes and his tailored slacks
Stab the motherfvcker in the back!
