Actually on Mythbusters they were trying to prove that Robin Hood couldn't have done it. The reason being is that he was using wooden arrows and the grain of the arrow would not allowone arrowto actually travel the entire length of the other arrow. The arrow would splinter off one way or another. That is a myth that cannot be busted.

BTW here is another pic of an expensive Robin Hood.
