When John isn't in the wrestling ring, he's granting wishes to children who are terminally ill. The WWE superstar currently holds the title for the most wishes granted by a celebrity for the Make-a-Wish Foundation, and in August 2015, he granted his 500th wish to an 8-year-old named Rocco, who's battling leukemia. In addition, John also serves as the Wish Ambassador Council for the charity and helps in expanding wish-granting access around the country.
