The following is an excerpt from the Monty Python sketch "Crunchy Frog". I think it rather neatly summarises the issue.
Inspector Praline: Mr. Milton? You are sole proprietor and owner of the Whizzo Chocolate Company?
Milton: I am.
Praline: Superintendent Parrot and I are from the hygiene squad. We want to have a word with you about your box of chocolates certified The Whizzo Quality Assortment.
Milton: Ah, yes.
Praline: (producing box of chocolates) If I may begin at the beginning. First there is the cherry fondue. This is extremely nasty, but we can't prosecute you for that.
Praline: Next we have number four, 'crunchy frog'.
Milton: Ah, yes.
Praline: Am I right in thinking there's a real frog in here?
Milton: Yes. A little one.
Praline: What sort of frog?
Milton: A dead frog.
Praline: Is it cooked?
Praline: What, a raw frog?
(Superintendent Parrot looks increasingly queasy.)
Milton: 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.
Praline: That's as may be, it's still a frog.
Milton: What else?
Praline: Well don't you even take the bones out?
Milton: If we took the bones out it wouldn't be crunchy would it?
Praline: Superintendent Parrot ate one of those.
Parrot: Excuse me a moment. (exits hurriedly)
Milton: It says 'crunchy frog' quite clearly.
Praline: Well, the superintendent thought it was an almond whirl. People won't expect there to be a frog in there. They're bound to think it's some form of mock frog.
Milton: (insulted) Mock frog? We use no artificial preservatives or additives of any kind!
Praline: Nevertheless, I must warn you that in future you should delete the words 'crunchy frog', and replace them with the legend 'crunchy raw unboned real dead frog', if you want to avoid prosecution.
Milton: What about our sales?
Praline: I'm not interested in your sales, I have to protect the general public.
