Basically any movie cover will do -- you know, holding the gun pointed up right next to your face?
You might want to look for the poster that's been on here before (I don't know where it is or I'd link you to it) with Al Gore looking down the muzzle of his M16, Dianne Feinswine pointing an AK right at Gray Davis, etc...
Hopefully someone will have a link to these.
