The Pink Stuff

Alex, describing what he learned in school today:

"Well, there's the bones, and then there's the pink stuff what helps you bweave."

"Lungs?" I asked.

"Yeah," he responded, eyes huge with amazement.  "How did you know?"

"I went to school, too," I said.

"Well," he continued, "when your lungs aren't working right, you cough."  (He pauses to legitimately cough, a side effect of his asthma which is flared up at the moment.)
 
"See, I coughed," he commented.  "So my pink stuff isn't working very well."
 
Only a few minutes later, he started singing a song under his breath about bones.  "Did you learn that song at school?" I asked. 
 
"Nope.  I just made it up.  It is from my song bwain.  I have lots of bwains.  There's my Wii games bwain, and my 'we have a Ben 10 game' bwain."
 
Maybe the reason he hasn't managed to eat his dinner yet is because he's just too full of creativity.
