Monty Python and the Quest for the Holy Grail - Which Way Did the Sword Go Through His Head?
In the part where King Arthur and his trusty servant Paxi are watching the two knights fight, at the end of the fight the black knight throws the sword right through the others head. STRAIGHT THROUGH. But when you see him take it out its sideways.
Actually, the black knight threw the sword into the head of the other knight at a little bit of an angle. Also, the killed knight falls on his side, not his back, so it would be a little sideways when pulled out.
Maybe the alive he had to jostle it around a bit or it fell that way, the dead knight's head isn't going to just hold it there, the law of gravity still is in effect.
