what's inside?

a couple of weeks ago, the science teacher at ozzy's preschool did a lesson on "what's inside?"  and the kids looked inside fruits, vegetables, chicken, and fish and saw the seeds and bones inside.  they also talked about the human skeleton.  ozzy was very interested in the idea that his body contained all those bones.  for several days afterward ozzy would question whether an object had bones.  mom? he'd ask, 'does this have bones?"  while holding up a dinner roll, or a potato chip, or a toy train, or a stuffed animal, or pointing to a bug.  and periodically he'd poke at a protruding bone on his own body and announce, 'yup, that's a bone there."  last night, at bedtime, as he snuggled down in bed in his relaxed repose with one hand down the front of his pants (i think that's like a genetic 'guy' thing), he seems to be in a pensive mood, he turns and asks me, "mom, does your pee pee have bones in it?"  not sure what he meant, i slowly said, 'um.  no."  he persists, "well, do KIDS pee pee have bones in it?"  still not sure what he was getting at, i say, "no."  he pauses a second, and then says, "well, I have a bone in my pee pee."  and i realize he's gingerly fingering his little penis and he's got a stiffy.  well, i couldnt help but laugh out loud.  and had to quickly excuse myself before he started to ask me any more questions about his boner.   omg!
