One time years ago, I saw this guy come out on stage with one of these expandable balls, similar to the photo below. He would open and close that ball as he went through his posing routine.
But, the funniest thing I ever saw was one night there was a guest poser. From just behind the stage left curtain, suddenly a silhouette of the edge of a big stomach appears. Then slowly the stomach moves forward, getting bigger and bigger. Finally the whole person appears. And it's Nasser!!! I laughed as hard as I could all through his whole routine. I kept thinking it's like looking at a cross between a bodybuilder and Santa Claus, his gut was so, so enormous. It thought it was just hilarious!!
