I used my Paul Harris like genius to come up with this erm...genius trick.
Required - pic/poster and envelope to fit, add a number pad or a pieces of paper, calculator.
Effect and method -
You predict a number in a dumb gag used mainly by 9 year olds.
Folks think of numbers and write on pad, someone else adds them up with calculator and total is 55378008. You say you predicted this and envelope is opened to reveal flat chested woman.
They look appaled/confused and you then turn calculator upside down - BOOBLESS
You can use a billet switch instead of an add a number pad if anybody is crazy enough to try this trick.
