Vince McMahon is the owner of WWE and he does what he wants to do. If a WWE Superstar needs help in doing a spot, McMahon would be glad to show the spot, even if it is a very dangerous one.
Becky Lynch recently spoke to TV Insider, where Vince McMahon was mentioned during the conversation. She talked about how McMahon demonstrated how to fall off “a tower” so that the Superstars knew how it had to look.
“Vince is such a larger-than-life character. At the same time, I watched him the other day demonstrate falling off a tower at 74-years-old without a bother, brushing his shoulders off and standing up again.”
WWE recently finished recording their two Money In The Bank ladder matches at WWE HQ in Stamford. So it is likely Lynch was talking about the tapings for these matches. We can hope whoever McMahon demonstrated the move to understood how to do it properly.
