French is basically set up to get les étrangers to accidentally make dirty jokes. Group two seemingly normal words together, and all of a sudden you have something sexual.
For example, when my grandmother was about to arrive in France, I said to my French friend:
Ma grandmère est très excité venir à Paris.
Literally translated, this means: “my grandmother is excited to come to Paris.” But, what I effectively said was “my grandmother is hot for Paris.” Excited, as I learned, does not mean how I use it in English.
