One of the wittier guys in the trailer park I grew up in did that trick where it looks like you can pull one of your fingers off from one hand. As an 8 year old that was fucking cool.

Another time he did the quarter behind your ear trick and then gave us the quarter.

To this day, I still remember it more than any other Milky Way or Babe Ruth candy bar I ever got. So yeah, go for it, make an impression.
