I found out something about a month ago, didn't share this knowledge, and now I forgot it. Shame on me.
Anyway, there are two resembling things I found out a while ago:
1. "Learning Curve" (tutor.it from JJ3 demo) is the title of an Ultimate Spider-Man chapter.
2. Darn, I can't remember. I'm thinking and thinking, but can't remember! Maybe somebody who I told this does remember.
