How many of heavyweight boxer George Foreman's 76 wins were won by knockout?

George Edward Foreman (born January 10, 1949) is an American former professional boxer, entrepreneur, minister, and author. In boxing, he competed between 1967 and 1997 and was nicknamed "Big George". He is a two-time world heavyweight champion and an Olympic gold medalist. As an entrepreneur, he is known for the George Foreman Grill.

Foreman took up amateur boxing and won a gold medal in the heavyweight division at the 1968 Summer Olympics. Having turned professional the next year, he won the world heavyweight title with a stunning second-round knockout of then-undefeated Joe Frazier in 1973. He defended the belt twice before suffering his first professional loss to Muhammad Ali in the iconic Rumble in the Jungle in 1974. Unable to secure another title opportunity, Foreman retired after a loss to Jimmy Young in 1977.

Ten years later he announced a comeback, and in 1994 at age 45 won the unified World Boxing Association (WBA), International Boxing Federation (IBF), and lineal heavyweight championship titles by knocking out 26-year-old Michael Moorer. He retired in 1997 at the age of 48, with a final record of 76 wins (68 knockouts) and 5 losses.
