Them: I SAW IT I SAW IT!
Me: THE PLAINE, THE PLAINE!
Them: What?
Me: I am sorry I thought we were immitating the midgit off paradise island.
They should be completly confused and dumfounded so continue with your magic.
-----------------------------------------------------
Them: I saw what you did!
Me: You did! I did not mean to honest! I ment no disrespect looking at your girlfriend ( if it is a girl ) I ment no disrespect adirming your body.
RUN LIKE HECK! lol
--------------------------------------------------------
Them: I know how you did that!
Me: Yeah it was pretty cool wasn't it? The way I mix up the cards.
They will freeze confused
--------------------------------------------------------
Them: I saw that!
Me: I HAVEN'T EVEN STARTED MAN! HE IS STILL HOLDING HIS CARD!
That only works when they still have there card obviously. Everyone will then laugh at him he will leave imberrised.
--------------------------------------------------------
Them mummbling to themselves: Did you see that!
Me: Nah I'm sorry I must have missed it.
That is reverse psychology.
--------------------------------------------------------
Them while watching my montie: I saw that!
Me smiles: No you didn't, but you just missed the move.
