Joke: Please Do Me a Favor

A dentist,after competing work on a patient ,came to him begging.
Dentist:Could you help me ?Could you give out a few of your loudest,most painful screams?
Patient:Why? Doctor,it wasn't all that bad this time.
Dentist:There are so many people in the waiting room right now ,and I don't want to miss the four o'clock ball game.
