I'm studying Russian, and one of my classmates came up with a little joke. We thought it was cute, nothing spectacular, though. All of our native Russian-speaking teachers, on the other hand, either don't get it or don't think it's funny. Here's the basic joke, I'll let you guys decide:
Отец сказал сыну, "повтори за мной, 'я буду хорошо водить себя'."
Сын шёл за отца и сказал "я буду хорошо водить себя."
So, is this just not funny in Russian?
