Question, what the heck is going on in that avatar of yours. I was highly amused when I saw it, but I am not sure what the heck is going on in it. 
It's from the second episode of
Monty Python's Flying Circus. It was a rather peculiar sketch (but then again, when did they ever do something ordinary?) about two French lecturers illustrating how they have upgraded a sheep to possess flying abilities. They show off a diagram with wheels, motors etc., as they pass their moustaches off to each other. Finally they start bouncing around while flapping their arms and shouting, "BAAA! BAAA!" Aah, the Python boys were/are brilliant.
