#1 The Undertaker burns Vince McMahon's teddy bear on WWE RAW

On the February 22, 1999 episode of WWE RAW, The Undertaker collided with Kane in an Inferno Match. The two stars made this stipulation famous, so it made sense to have them try to set each other on fire on WWE RAW.
At the time, "The Phenom" was the leader of a legendary faction named the Ministry of Darkness. His goal was to take over the WWE by any means necessary. Of course, this quest created a conflict with Vince McMahon. The Undertaker sought to rule WWE, and McMahon desperately wanted to stop him.
"The Boss" punished The Undertaker every chance he got. But "The Deadman" ultimately made him pay. After this Inferno Match, The Undertaker burned McMahon's favorite teddy bear. McMahon was so distraught that he fell to his knees and cried.
As it turns out, the teddy bear belonged to McMahon's daughter, Stephanie, when she was a child. This moment remains one of WWE's most bizarre usages of fire, but it's certainly memorable.
