#3 Brock Lesnar vs Hulk Hogan
Although this incident actually happened inside a WWE ring, it was as real as it could be! On the road to Summerslam 2014, Hulk Hogan celebrated his birthday on an episode of Monday Night Raw, with several WWE legends and Hall of Famers alongside him. The party was soon crashed by Paul Heyman and Brock Lesnar, who proceeded to shove Roddy Piper and get in Hulk Hogan's face. Brock then uttered those infamous words, "Party's over grandpa!".

Reportedly, Brock came up with the line himself and it wasn't a part of the script. Hogan was said to be furious after the incident and wasn't thrilled with Brock referring to him as grandpa. The Hall of Famer later gave a scathing statement, warning Brock Lesnar of serious consequences if he ever did the same again.
