C: Well, I thought I could get the leg bladder, but it's too small, so I didn't get credit.
M: What's a leg bladder?
C: It's like a small leg bladder.
M: But what is it?
C: You know how there can be a bladder? It's like something hollow in the leg.
M: Like a swim bladder? In fish?
C: [looks at me] Yeah.
M: Do you know what that is?
C: Huh? I don't know....
M: It's a biology term. I don't think you've heard of it. So, what's a leg bladder?
C: [looks really confused] I don't know what that is.
M: You were just talking about it.
C: I was?
M: Are you awake now?
C: Yes. [pokes my cheek]
M: Are you a professional?
