why'd you have to go and make things so complicated?

If you thought Rock, Paper, Scissors was complicated (well, okay, no it's not and it shouldn't be, especially when there's a strategy guide online), you should try out Rock, Paper, Scissors, Spock, Lizard or RPSSL, which has two additional hand signs, Spock and Lizard.

Scissors cuts Paper covers Rock crushes Lizard poisons Spock smashes Scissors decapitates Lizard eats Paper disproves Spock vaporises Rock crushes Scissors.

But no, it has to be made much more complicated, because sometimes when you're playing with a friend you know really well, you already know what they'll come up with. So on top of RPSSL, someone actually came up with RPS-15 which has fifteen hand signs. The thought just boggles the mind.

That is what happens when people have a lot of time in their hands.
