#4. Shane McMahon exchanged gifts with The Undertaker following their WrestleMania 32 match
Shane McMahon made an explosive return to WWE back in 2016 and was then forced to wrestle The Undertaker in a Hell in a Cell match at WrestleMania 32.
The match had major implications regarding the control of the company riding on it, but McMahon came up short despite a dive off the top of the cell and through the announce table.
After the match, it appears that he earned the respect of The Deadman since McMahon revealed in an editorial for ESPN ahead of The Undertaker's retirement that the two men exchanged gifts.
“I always have extra baseball jerseys made for important events, so I presented one to him after the match, and as I was doing that, he was giving me one of his [MMA-style] gloves. That old-school appreciation.” - H/T ESPN
McMahon later went on to become the Commissioner of SmackDown despite the loss, whilst The Undertaker announced his retirement at Survivor Series 2020 after a career which spanned over 3 decades.
