I can't believe I'm actually going to post this. But, I almost fell over laughing when I heard this, so I have to record it.
Jack was awake, lying in his bed. I went in and was talking to him for a little bit, when this gem came out. "My peepee is growing."
I managed to keep a straight face and not comment, but he wasn't done.
"When you play with peepees, they grow."
Still not commenting, still a straight face. Until....
"Like a beanstalk! You know how beanstalks grow and grow?"
Yup, almost fell off the edge of his bed, I was laughing so hard.
