5 Biggest Brock Lesnar moments you probably didn't know were actually unscripted

#2 Brock Lesnar's controversial promo when he crashed Hulk Hogan's party

Brock Lesnar and Hogan

John Cena and Brock Lesnar resumed their 2012 rivalry on the road to SummerSlam 2014. Cena was the WWE World Heavyweight Champion at the time and The Beast was determined to go to great lengths to win the belt. Mere days before the event, WWE celebrated Hulk Hogan's birthday on RAW, which saw a string of legends and Hall of Famers appearing alongside Hogan. Lesnar came out with Paul Heyman and crashed the party.

He confronted Hogan, and uttered the words, "Party's over, Grandpa!" It was later revealed that Lesnar's words were completely unscripted and it was The Beast himself who came up with the line. Hogan was clearly upset at what had happened and later expressed his anger over the promo.

It’s not cool brother. I know this is all entertainment. You know we’re supposed to have fun with it but when he starts throwing my name around, with my wife and my kids, it’s crossing the line.

As was expected, Lesnar didn't respond to Hogan's comments. He went on to squash Cena at SummerSlam to win the WWE World Heavyweight title.
