[Okay, it's obvious that BB has lost his mind. Or is in a nightmare. At least Private is able to keep a good enough sense about him to NOT freak out.

But he needs to knock him out of it some how, so he uses the fact that his friend is distracted and probably not all that balanced to do a hard belly slide right in to his feet, hoping to knock him over.]

Sir! Snap out of it! It's a nightmare, it's not real!
