Snow White and the Seven Samurai

The Brain: Pinky, are you pondering what I'm pondering? 

Pinky: I think so, Brain, but then it'd be Snow White and the Seven Samurai

Houston, we have a BIG problem

A sense of humor

It is better in the long run to possess an abcess or a tumor
Than to possess a sense of humor
People who have senses of humor have a very good time
But they never accomplish anything of note, either despicable or sublime
Because how can anyone accomplish anything immortal
When they realize they look pretty funny doing it and have to stop to chortle
