dart joke

A man goes into a strange pub and starts chatting to some of the local darts players when they ask him if he wants a game. He says "I have never played a game of darts before but I will give it a go if you tell me what to do."

After playing for about an hour he has not lost a single game and has hit some fantastic shots. One of the players says to him "I thought you had never played before?"

The man replies "No I haven't, but there are a lot of flies in my flat and I have got some old darts which I throw at them and pin them to the wall."

"No wonder you are so good then if you can do that. But doesn't it make a mess on the wall?"

"Not really" replies the man "Because I only pin them by their back legs."
