For those of you who haven't watched the classic film "The Good, The Bad, And The Ugly":
Blondie (Clint Eastwood) and Tuco(Eli Wallach, scroungy Mexican bandit guy) have each 
learned half of the secret of
where $200,000 is buried. Blondie knows the name of the grave, and Tuco which cemetary it's in.
In the climactic scene, they've reached the cemetary, and dug up the name Blondie earlier revealed to Tuco.
At that moment Angel Eyes (Lee Van Cleef, dressed in black) appears and gets the drop on them. So Blondie reveals the grave's empty, and offers to write the real name on a stone if Angel Eyes will put his gun away. Then they have a 3 sided duel over the stone.
