During his sprinting career in the 1990s, Johnson captured four gold medals for Team USA, including becoming the only man to win the 200m and 400m races at the same Olympic games.
In 2018, Johnson suffered a stroke, but has since recovered and is all smiles as he poses with his pint of the black stuff.
