Because the original's too basic, let's play a game of Rock Paper Scissors Lizard Spock!
Its first use on The Big Bang Theory is to settle a debate about what to watch on TV between Sheldon and Raj - appropriately on the episode "The Lizard-Spock Expansion".
When used on the show, the boys almost always choose Spock every time, causing ties after ties after ties and basically never ending the game.
A brilliant design for all Big Bang Theory fans to enjoy!
