One of the revolting confectionarys mentioned in a Monty Python sketch about a dubious candymaker. Starring John Cleese, Graham Chapman and Terry Jones.
The sketch appeared on three of their albums, in episode 6 of their "Flying Circus" show, and in the movie "Live at the Hollywood Bowl". All instances were performed live.
Other vile confections mentioned are 'Ram's Bladder Cup', 'Cockroach Cluster', 'Anthrax Ripple',and 'Spring Surprise'.
Cleese: Next we have number four, 'crunchy frogs'.
Jones: Ah, yes.
Cleese: Am I right in thinking there's a real frog in here?
Jones: We use only the finest baby frogs, dew picked and flown from Iraq, cleansed in finest quality spring water, lightly killed, and then sealed in a succulent Swiss quintuple smooth treble cream milk chocolate envelope and lovingly frosted with glucose.
Cleese: That's as maybe, it's still a frog.
Jones: What else?
Cleese: Well don't you even take the bones out?
Jones: If we took the bones out it wouldn't be crunchy would it?
