Worried Mother
 

A mother worried about her sons behavior took him to see a psychologist.
The Dr. said son what is it you really like doing? The little boy said I like to kill birds with my slingshot. The Dr ask why do you like to do that ? The kid said I think it's fun. The Dr said what else do you enjoy doing? The kid said I like to make slingshots. The Dr said I see.
The Dr said well when you are not killing birds and making slingshots what else do you like to do.
Well the little boy said I like to pull down little girls panties. The Dr said ugh huh now we're getting somewhere. The Dr then ask well son what is it you do when pull their panties down? The little boy looked at him and said I take the elastic out of them to make slingshots to kill birds.
