In Tom Stoppard's play Travesties, one of the characters says about
Switzerland, “What a bloody country even the cheese has got holes in
it!” I know I've heard this saying before. Two years ago, I searched
for the author and figured out (I'm pretty sure this was through a web
search) that the author was La Rochefoucauld. Now, I can't seem to
find this quotation anywhere on the internet (I've even tried typing
it in French!). I'd like to know who said it and whether the source
can be cited or the attribution is apocryphal. Thanks!

I haven't been able to turn up a connection with La Rochefoucauld, but
I would wager that Tom Stoppard did not originate this.

Although I can't give you an exact citation, I am sure that I saw this
quote used by P.G. Wodehouse in the 1920s or '30s. It certainly sounds
like something that Jeeves' airheaded employer, Bertie Wooster, might
say.

I hope another Researcher has better luck digging up some hard
evidence. This is one of those questions that is going to nibble at my
brain until it is answered. ;-)

Thanks, Pinkfreud, for attempting to answer. Unfortunately I am not
very familiar with Wodehouse. Hopefully someone will figure it out!
