Put a spool of thread in your pocket. Threads should be contrasted in color with your clothes. You can thread the tip of the thread into a needle and bring it out so that it would appear either as a thread that has emerged in the seam or as if adhered to a sleeve or pocket or a lapel with a piece of thread do as you please. Someone will certainly notice and tell you about it, and you will ask him to remove the thread. And then the funniest thing will begin.
