Aiming for the head...? That's pretty badass. Something I'd imagine from a Jackass movie, though, to think of it.
Since the body was generally covered by the shield, which was curved to deflect the lance and minimize the impact, aiming for the head was a difficult yet successful strategy. There is tale of a English knight that won a jousting tournament, and when they went to award him for it, they found him kneeling at the blacksmiths anvil having his helmet removed, which had been spun and stuck 180 degrees around.
