good old earwig, nothing beats it*

From Bowles, Microeconomics:
In the children's game, common around the world (English speakers call it "Rock, Paper, Scissors" and for others it is "Earwig, Human, Elephant") there is no Nash equilibrium in pure strategies.
Earwig, Human, Elephant? Really? What beats what in Earwig, Human, Elephant? And how do you make your fingers look like an earwig? Anybody know?

* Reference to Simpsons exchange:
Lisa:  Look, there's only one way to settle this.  Rock-paper-scissors.
Lisa's brain: Poor predictable Bart. Always takes `rock'.
Bart's brain: Good ol' `rock'. Nuthin' beats that!
Bart: Rock!
Lisa: Paper.
Bart: D'oh!
