Me: Are there any questions?

(Student raises hand.)

Me: Yes?

Student: Is that your other earring out in the hallway?

(I checked, and yes, it was. So much for dignity.)

Student: How would you ask where the bathroom is?

Me: Well, there are several ways, but the simplest is probably "Ou sont les toilettes?"

Student: (dreamily) Even toilet sounds beautiful in French!
