5 Times WWE let their Superstars compete for other companies whilst under contract

#1. John Cena and Mr. McMahon in a high school gym

Both Cena and McMahon competed at a high school gym in 2007.

When fans sat down to a Chaotic Wrestling event in May 2007, few knew what was going to happen. A charity show to raise funds Newbury Police Association, everyone attending was encouraged to give big and were given a huge prize in return by the appearance of then-WWE Champion John Cena.

Serving in a special guest referee role, Cena wasn't the only big star on the show, as WWE CEO Vince McMahon also made a shock appearance, and during the main event tried to attack the 16-time World Champion, only to be levelled by an FU. A shocking night for everyone watching, it was a classy move by WWE to allow Cena to perform at the high school gym as Big Match John definitely helped bring in big donations for the Police.
