Boxing legend and famous grill salesman George Foreman named all of his sons after him: George Jr, George III, George IV, George V, and George VI.
"If you're going to get hit as many times as I've been hit by Mohammad Ali, Joe Frazier, Ken Norton, Evander Holyfield - you're not going to remember many names."
He also has a daughter named Georgetta, and another daughter named Freda George. The rest of his daughters aren't named after him.
