Hitlery's should be in the shape of a serrated knife (for a well-placed hit in the back) or twisted screw (that's what she does to people when they're not looking).
or a big ole mouth
or a uterus.
It seems like a line from the Pink Floyd song "Dogs" (from the album "Animals") was written just for the Clintons...
"You have to be trusted, by the people that you lie to... So that when they turn their backs on you, You'll get the chance to put the knife in..."
