Batman takes a lot of notes using the Batman Gel Pen 2-Pack. He takes notes on his enemies; how to beat the Joker, how to get Danny DeVito to be the Penguin again, and what was up with Jim Carrey as the Riddler. Oh, he also takes notes on how to get chocolate chip cookies to get extra fluffy and different ways to manipulate kittens with string and boxes. Those last two don’t really happen all that often in the comics. Say, you know what you need? The Batman Gel Pen 2-Pack!
