However, he failed to do the same thing with Randy Orton. As soon as Undertaker opened the casket, Bob Orton sprayed a fire extinguisher that temporarily blinded Undertaker. He was then thrown in by Randy Orton who then sealed the casket to win the match.

After repeatedly hitting the casket, Randy Orton and his father poured gasoline all over it and set it on fire. Everyone inside the arena got up to their feet as they acknowledged the cruel actions carried out by the father-son duo. Randy Orton stood there staring in shock as Undertaker’s casket was burning in flames.
