What I do when this situation arrives I repeat back what they said like " Oh two cards huh? That's what you saw well thats interesting we'll try it again watch this,...hold the card assuring there's just one and place it sticking out of the deck anywhere you want", and then do a half pass and it shuts them up usually and most of the time they think your better for it. Try it and let them play their games and well play ours you will conquer when its over. Usually I'll get a reaction like" Oh I hate you!", in a funny way of course and since you didn't lose your temper they forget you even screwed up in the first place or they think it was part of the trick. It works for me.
Thanks for the advice, but i don't know how to do any passes. I will have to learn. What books/DVS's can i get that teach it?
And, i can also work on my DL's a bit more so they dont' catch me...
