At the darts match

[spirit6060]

Three nuns go a darts competition and sit in the front row to be near the action.
The first darts player comes up and throws and treble twenty. His second dart got a twenty. His third dart hits the wire and ricochets and hits one of the nuns in the head. She collapses to the floor - obviously no longer in this world.
The scorer shouts out :

one-nun-dead-and-eighty!
