#4 Punk piledrives Cena into oblivion
The long-term rivalry between CM Punk and John Cena is one of the best stories ever told by WWE. The reason the fans were so invested in this storyline is that there was a touch of realism to it. Even the infamous pipebomb by CM Punk that catapulted him to greatness, came during their feud.
During one of their matches on Monday Night Raw, Punk gave Vince even more reason to be furious with him. Out of nowhere, Punk gave Cena a Piledriver in the middle of the ring, shocking the audience, since the piledriver in the form given by Punk had been banned from WWE for a long time.
After all, the exact same piledriver cut short Steve Austin's career, after Owen Hart botched the move in their match. Only The Undertaker and Kane were allowed to use the move, that too only a reverse-piledriver (or Tombstone piledriver) variant.
Vince is said to have been furious backstage. Reportedly, Cena trusted Punk enough to let him perform the move on him, and because of this both the performers were allegedly slapped with hefty fines.
