One way to open the "RE: Games" episode would be to have two characters are in a heated battle of Rock, Paper, Scissors. They are sweating as their eyes are locked with intensity. Their hands are twitching and they're getting ready to play the game.
They each pump their fists three times and on the third pump one of the characters reveals a flat hand - paper - and the other has a real rock in their hand and they throw it at the head of the other character, who gets struck and holds their head in pain.
The cheater is victorious and handed a trophy with a large celebration of chearleaders and confetti while the other guy has a huge lump on their forehead and is wincing in pain.
