"Escape artist Amazing Joe Burrus, a recovering drug addict, wanted to give back to society by performing a Houdini-like stunt for a rehab-clinic benefit in 1990. For the act, he was covered under six feet of dirt and wet cement in a locked coffin while bound in chains and handcuffs. After the nine tons of glop were poured on, the coffin
collapsed and Burrus was buried alive."
