Let me do some Dutch words.
I once shocked some people on an E-hell thread when I was talking about panties
in a thread about pantyhose.
(There are more languages in which pantyhose are called panties, so somebody quickly figured out what I meant and posted it)
On used car lots you will see big signs here saying OCCASION. WHen driving by one once with my American ex-GF, I for some reason read the sign out loud pronouncing it correctly with a French accent. See thought that I was joking with funny accents, and that is when I realized that she read it as the English word.
occasion (eng): occurence
(d')occasion (fr): 2nd hand car
