Survival of the fittest

Used to describe Peter and Fran’s approach to Disney World.

Fran to Peter: Why did you scare the little boy at the front of queue so much that he shat himself.

Peter to Fran: So that his parents had to leave the queue with him, reducing our wait time from one hour thirty-six minutes to one hour thirty-four minutes. Survival of the fittest.

Fran to Peter: Bravo my Prince Charming. Now watch me beat to death that old woman spending too long with Mickey. Survival of the fittest
