It makes me think of other useless information that I have memorized. When Nate was 2 1/2 he loved Dr. Seuss ABC's. I had that sucker memorized by the time he had his ABC's down. Then he went to Kindergarten and that is the book they use to teach the alphabet. Oh, and they turn it into a song. So then I could sing the song. That info faded in my mind, returning randomly when Lily pulled out that book. Then of course she starts Kindergarten, and it's stuck in my head again.

I have an easier time memorizing things that are turned into a song. I can still sing the 50 states song that I learned in 5th grade. It has come in handy a few times (Jeopardy questions) so I can't say this was useless information. So maybe if we can put Biology to music, I'll be able to explain the life cycle of moss.
