The Incident

Rock Paper and Scissors discover child versions of themselves.

Paper is the smartest of the three so he tracks their cartoon counterparts and does some spying. However jealousy finally pushes him to the deep end and he puts and end to Cartoon Rock Paper and Scissors in the most brutal way possible.

Disclaimer: I don't know who the Rock Paper Scissors counterparts are but I'll be calling them Cartoon Rock, Cartoon Paper and Cartoon Scissors.
