i did an entire routine today based on this idea... a girl who's seen me do pretty much everything i do asked to see a trick so i said ok, i had to improv, its a great exercise for any art i feel. what i did was shuffled, and i *cough, pal cough, med* her card. and followed with " you shuffle" so she did, i walked a ways a way and leaned against the wall, she said, "ok, now find it" and i said, "you find it" and i pointed to the card case back over by her she freaked, i'm gonna call that lazy web's card trick. its not original by any means, but the presentation might be. so try to use that urge to your advantage if and only if you can't prevent it. notice she didnt ask to shuffle, i offered.
