6. Once In A Lifetime
The Rock nails John Cena with a Rock Bottom, the conclusion to their 'Once in a Lifetime' match in the main event of WrestleMania XVIII.
As far as inter-generational dream matches go, this was probably the biggest since The Rock took on Hulk Hogan in 2002 - but this time, the Brahma Bull was the returning elder statesman, looking to take out the all-conquering John Cena.
To the surprise of many, he actually did! Capitalising on Cena's cockiness in going for a People's Elbow, Rocky sprang to his feet and planted his opponent with a Rock Bottom - winning thousands of casual fans back into WWE's fold in the process.
