Two assassins are hired to kill a dictator in South America. They follow his every move for months, and find out that every day at noon he goes outside and does his stretching exercises.

So the assassins set up shop right across the street, get all of their sights set, load the guns, and have everything ready to go.

Noon comes, no dictator... 10 minutes longer... no dictator.

One assassin turns to the other and says, "Gee, I hope nothing happened to him."
