Non-Polar Bear

A two-headed polar bear, like a Pushmi-Pullyu, as seen in the CrashCourse Chemistry episode, Polar and Non-Polar Molecules.

Me: What is that two-headed polar bear? It looks cursed!
My chemistry teacher: It honestly reminds me of the Pushmi-Pullyu from Dr. Dolittle.

Me: Guess I should call it a non-polar bear.
