Quick rock paper scissors question

[Ishfay]

I insist that its paper.

How does the person react to this? Act like it was a brainfart? Try to screw you by saying it is paper or scissors to whatever is their benefit?

Sidetrack:
A friend of mine came up with a weighted rock paper scissors. If you win w/ rock, you get 5 points. If you win w/ paper, you get 2 points. If you win w/ scissors, you get 3 points. Play to 15. It just increases the levels of mind games. Its awesome.
