My favorite is I was playing with my cards in an eating area and a person and his friends asked if I did magic I said I did and they asked to see something. So I asked him to name any card and he said four of hearts. So I riffled through the pack and pulled out a random card and it just so happened to be the four of hearts. They freaked out and another guy asked me what he was thinking of right now. I of course had absolutely no idea but I tried to act like I did and I just said as I shuffled my cards, "an orange". This guy flipped out because he was thinking of an orange. And these guys literally ran away. Best day ever
