You had me until squid axon

I was especially groggy this morning which is why I accidentally used my roommate's toothbrush. Pathophys started at 8:30 and I still wasn't fully awake and having trouble following what seemed to be an especially circuitous and convoluted and confusing and torturous lecture about membrane potentials and depolarizations. I wasn't alone - looking around the classroom it seemed that everyone had glassy eyes. The professor was wizzing through the overheads and she finally put up a graph to demonstrate an action potential in a nerve which was labeled "squid axon" and it was just too much for the class. M spoke up and said "excuse me, what's a squid axon?" It's a crazy question when you look at it independent of context, but imagine a roomful of weekend-spent students trying to follow a confusing lecture that's presumably about potassium imbalances and suddenly there's a fish thrown in for fun... The professor explained that it was indeed the axon from a squid and another classmate said "oh, you had me until squid axon."
