"The Purity of the Turf" is a short story by P. G. Wodehouse, and features the young gentleman Bertie Wooster and his valet Jeeves.

The story was published in The Strand Magazine in London in July 1922, and in Cosmopolitan in New York that same month.

Steggles, who organized the Sermon Handicap, is offering bets on victors for contests at the fair.

Jeeves recommends they place a bet on Harold, an underestimated contestant, for the Choir-Boys' Hundred Yards Handicap.

To make up for their loss over Harold, Jeeves tells Bingo to bet on Prudence Baxter for the Girls' Egg and Spoon Race.

Just as Bertie starts to mourns his losses, Heppenstall announces that a servant—implied to be Jeeves—has confessed to paying several participants in the Girls' Egg and Spoon Race to finish.

The episode–entitled "Jeeves and the Purity of the Turf"–was the fifth episode of the second series and was originally broadcast on 1 February 1966.
