lost ball in golf

George was standing at the first hole tee watching other play off.
His pal John came up and asked why he wasn't playing.

George " I am loosing too many golf balls ,I keep slicing the shot and I loose them in the long grass"

John " What you want George is a ball like this. If it goes into the long grass is sends out a loud sound so you can find it"

George" That is no good either, sometimes I slice the ball and it goes into the wooded area and I can't find it"

John " George I tell you this is the type of ball you need. Not only does it send out a loud sound in the long grass, but in a wooded area up pops a flag and starts waving about"

George " John that is amazing, where can I got one like that from?"

John " I don't know I found this one"
