"Crunchy Frog" is the common name for a Monty Python sketch officially titled "Trade Description Act" (sometimes also known as the "Whizzo Chocolate Company" sketch), inspired by the Trade Descriptions Act 1968 in British law. It features two health inspectors interrogating the owner of a sweet shop about the increasingly bizarre ingredients in his confections, including the titular crunchy frog. Written by John Cleese and Graham Chapman, it originally appeared in episode 6 of the first series of Monty Python's Flying Circus, and later appeared in several Monty Python stage shows. In the original sketch, Cleese and Chapman play the inspectors, while the sweet shop owner is played by Terry Jones. In later versions, the second inspector is played by Terry Gilliam or left out of the sketch entirely.
