Two terrorists decide to kill an important government official.
At 10 o'clock the next morning, they meet across the street from a building where the president is scheduled to have a meeting, and one of them brings a rocket propelled grenade launcher.
Ten o'clock comes and goes, but no president. Then eleven o'clock. Eventually it's noon and the president still hasn't arrived.
One terrorist turns to the other and says, "Gee, I hope he's okay." 
darn good one
