Dan is joined by the QI Elves James Harkin and Anna Ptaszynski to talk about cheating in sports as the 2024 Olympics get underway. Why do we do it and how far back does it go? From the man who jumped into a car during the 1904 Olympic marathon to the Puerto Rican twins who swapped places in the Los Angeles Games long jump, here are some of the most audacious stories.

James Harkin and Anna Ptaszynski have a new book called 'A Load of Old Balls: A QI History of Sport'

Produced by Mariana Des Forges and edited by Max Carrey.
