a guy buys a used greyhound & decides to race it, he tells all of his friends to bet money on it,the 1st time he raced it,it kept veering to the left instead of runing in a straight line, one of his friends said I know how to cure it ,put some lead in it's right ear, the guy said how'm I going to do that & his friend said wth a gun. Please note that no animals were harmed in the making of this joke.
