TJ's of the opinion that everyone should love musical theater. Preferably best with large dance numbers. So he can, y'know, have a job in the future. *laughs*
That memorization vs. math/languages? I so totally know from personal experience. I'm on the math/lang side myself... and the trick Jackson uses (setting everything to cadence/music so he can remember it) is how I managed to survive history. This is why Jackson can remember any song lyrics... but not dates of wars!
