Behold the awesome power of the dumbest weapon of all time against a race of complete idiots - the light grenade.
http://www.youtube.com/watch?v=iEEIaRUWzOA"This is one of the weapons we stole from them, it's called a light grenade. You pull the pin and set it down. Then when someone picks it up, poof, grenade remains but the person is gone."
"Why would someone pick i t up?"
"Look." *turns grenade over, on the other side it reads* 'Pick me up.'
"Pick me up?"
"Yes, diabolical isn't it."
*sighs and shakes head* "Let's hope they're as stupid as everything else on this planet..."
