So all semester in neurobiology, we've had weekly "interactive case studies" that we had to complete online. Basically, the instructors have found a number of animals over the years with certain neurological problems. They then videotape a complete neurological exam of each animal (testing reflexes, proprioception, pain sensation, etc.).
As the cumulative portion of our final exam, we had 4 case studies we had to complete. The first one was of a cow with some neuro problem that we were supposed to figure out based on the results of the neurological exam.
The case in itself wasn't really all that fascinating - it was pretty run-of-the-mill as far as the requisite logic/reasoning/thought process was concerned.
But the best part came at the end of the first video clip, in which the examiners were just walking the cow around on a rope head halter, to observe any abnormalities in how the cow was walking or moving.
At this point, I need to let you know that this neuro exam was taking place on the main campus, not at the teaching hospital; i.e. they were walking the cow around on a grassy lawn between some of the academic buildings.
Anyway, I gather that cows don't usually like to walk on a halter and lead quite as much as some other species do. This cow certainly wasn't too thrilled about it.
The video clip culminated with the cow struggling mightily against the rope halter, eventually starting to pull the halter off her head, at which point the cameraman puts down the camera and runs over to help the other 3 people doing the neuro exam. The last thing we see is the cow, completely free from any halter or lead or restraint, wandering off into a parking lot with 4 people going after her in an urgent manner.
(Moral of this story? Maybe don't do your neuro exam on a cow on an academic campus with just a makeshift rope halter for restraint... or you risk having the ensuing hilarity recorded on videotape for countless generations to observe!)
