I read about an incident where Max Malini had aparently bitten off the button of an influantial U.S senator's shirt in Washington D.C. The senator was upset and outraged but Malini said, "wait", and proceeded to spit the button back onto the shirt restoring it entirley. This sounds like a very cool trick and if anyone knows where to get this trick or routines surrounding it, it would be most appreciated for any info regarding this trick.
