Pygmy.

An explorer is making his way through the jungle when he steps into a clearing. An elephant is lying in the middle of the clearing. He carefully approaches the elephant and discovers it's dead. He then notices a 2 foot high pygmy standing by the side of the elephant.
"Did you do this?" he asks the Pygmy.
"Yes, I did it with my club." replies the pygmy."
"Blimey, how big is you club?" asks the explorer."
"There's about sixty of us." replies the pygmy.
