Rock, Paper, Scissors, Lizard, Spock

I walked into Chick-Fil-A Friday morning to get my usual treat. Friday is casual dress day at work, so jeans and a t-shirt are a must wear.

As I walked up to the counter, the gentleman taking my order began staring at my shirt. He soon had a confused look on his face.

I proceeded to point to the symbols on the shirt, and explained that they were "rock, paper, scissors, lizard, Spock.

Still confused, he replied "Huh, I don't know any sign language".
