I came up with a great cover act, but haven't had the guts to try it. Here it is, free for the taking. Just let me know how it goes if you use it.
Tourettes
Saw a guy with tourettes syndrome playing bj once. Every now and then he would yell something out or have a twitch or spasm.
It is a great cover act. Who would ever think a guy with tourettes could be counting cards.
