Caffeine Mug for Chemists - Clean Up Structure!

You. You know who you are. You know EXACTLY who needs this mug... Background: My mother gave me a caffeine mug once when I was a freshman undergrad. It had the worst-possible caffeine structure on it. Bonds and bond angles all off. The works. Who comes up with this?! But it was a gift from my mother. So I kept it. In the back of the cabinet, where nobody else could see my shame. Fast forward to a decade later, when I had just unpacked that mug from another move, and I realised that there was a way to redeem its sorry structural mishaps. I grabbed a red sharpie, and made it into a work of art any chemist with an ounce of teaching experience could appreciate. Now it's sitting out near the kitchen table. I still haven't put coffee in it, but at least it's not hiding anymore.
