'I invented the Mexican Wave'

On 15 October 1981, at a baseball game between the Oakland Athletics and the New York Yankees in the USA, American cheerleader Krazy George Henderson got fans to stand up and sit down in sections around the stadium.

When crowds at the 1986 World Cup in Mexico joined in, it went global, earning the nickname the Mexican Wave.
