9. John Cena Pees On Some Unfortunate Soul's Grave - SmackDown 2003
One of the biggest missed opportunities in recent years in WWE was that they never booked John Cena vs. The Undertaker after Cena became the biggest star in the company. It would have been a tremendous main event level match for WrestleMania with someone who fans could reasonably believe had a shot at ending The Streak. However, they did feud during Cena's ascension, when he was a cocky heel rapper. To show he wasn't afraid of the Undertaker, he did a rap from a graveyard at night, ending with this rhyme:
At Vengeance, I'm 'a prove the big dog is all bark. I'm 'a claim my territory, piss right on the mark. WORD LIFE!
Then he literally peed on someone's grave. http://www.dailymotion.com/video/x1xfkf_cena-raps-on-undertaker-in-graveyar_sport They never said whose it was. That's just...weird. Was he trying to anger The Undertaker about the principle of the matter instead of getting to him personally?
