At least 75% of the time a trick is requested, it's this one. This is the trick everyone remembers
me for, whenever I'm introduced as a magician they almost always tell the person of the time I did
this trick. While not impromptu, you can set it up if you have 10 seconds to yourself, and if you're
really good as far as cards go you can actually have it set up in advance to repeat the trick. I
once had to do this trick 6 times in a row at a large party as one person kept grabbing new people
to see it. I know I was breaking one of the most important rules of magic, performing the same trick
for the same audience, but I couldnt resist. Two caveats: first, I have had some audience members
figure out the trick, as it's not overly complicated, but almost every time the crowd explains why
they didnt get it right (even though they did) and they end up looking like idiots. Second, this
trick involves very basic slight of hand, sleights every magician should know, but probably the most
common sleights magicians avoid. So, any intermediate or advanced magicians need to get this trick,
any beginner magicians need to get Born To Perform by Oz Pearlman and then get this trick.
