A colleague of mine who works with special education students recently had a 4th grade male student approach her. The boy, who is highly autistic, asked, "Mrs. Soandso, do you know what wee-wee is?"
This would be an uncomfortable question for just about any teacher. With autistic kids, one can't always be sure what they're going to do with the information, how (or when) they might repeat it, etc. Still, the teacher also wanted to be make sure that the student wasn't involved in some sort of abuse issue.
"Um, well, sweetie, a wee-wee is a body part you have between your legs."
The boys burst into hysterical laughter.
"What are you talking about!?" he shouted still laughing. "Wee-wee is what French people say!" and he laughed himself blue in the face.
Teachers... they always have their mind in the gutter.... :)
