Theres an Austrilian comedian Adam Hill he only has one leg, He was on QI when he told this story.
He was sunbathing on the beach with his leg standing beside him.
A child and his mother were walking by and Adam heard this:
The child was speaking to his mother telling her what a great day he had: the waves were big and I’m sure I seen a shark and……. then he spots Adam and shouts THAT MAN ONLY HAS ONE LEG!!!!!
Adam said the mother turned pink while he just lay there laughing.
