by Rick Springfield.

Here are the relevant portions of the lyrics.

? When you were just a young girl and still in school
How come you never learned the golden rule
Don?t talk to strange men, don?t be a fool
I?m hearing stories, I don?t think that?s cool

Why don?t you tell me, someone is loving you
Cause you?re my girl, some say it?s no longer true
You?re seeing some slick continental dude
I?m begging you, please?
