Two elderly nuns are at their local watching a darts match.
The first player throws his initial dart and scores a maximum treble twenty.
Then he sees the nuns and it puts him off his stride and his second dart scores only a twenty.
The nuns express their disappointment but try to cheer him on.
By this time he is losing his cool completely and his third dart hits one of the dartboard wires and rebounds to the place just where the nuns are stood.
Sadly, the dart hits one of the nuns and the other is so shocked that she drops dead.
The crowd is silent for a moment
... and then the referee shouts out in his broad Geordie
"One nun dead and eighty!"
