Danger Ehren kills Jimmy Kimmel

Prank is played on Ehren: Have Johnny knoxville and Danger Ehren on Jimmy Kimmel with the premise that Johnny is going to do some trick with a gun.  When Johhny and Ehren are on the set, have a reason for Johnny to give the gun over to Ehren and have Johnny tell Ehren to shoot it at Jimmy with the idea that the gun isn't loaded.  The gun will fire a blank and Jimmy will have a blood packet in his chest go off and will pretend to have really been shot and then die.  Soon as this happens, Ehren is tackled by security, and subsequently arrested for murder.
