McMahon was already in good condition, and he obviously knew how to properly fall backward over a table. If you take the wrong senior citizen and push them backward over a table, they could end up in a splint, a wheelchair or lying flat on a gurney.
Then there’s Bubba Dudley throwing 80 year old plus and “preggos” May Young (is old) through a table.
One of the greatest WWF/E moments ever.
