Where Do They Learn This Stuff?

Brennan has been sick for a few days with a fever of 100-103 or so.

Today when I woke him up so we could take Bart to work, he sat up, felt his forehead, and said, "Well, I guess my fever broke. My brain is cool."

Where the heck did he learn the phrase "fever broke" and how did he know how to use it properly???
