Dirty Deeds Done Dirt Cheap (Angus Young - Malcolm Young - Bon Scott)

well if you're having trouble with the high school head he's giving you the blues you want to graduate but not in his bed here's what you gotta do pick up the phone, I’m always home call me anytime, just ring, 362436 oh I lead a life of crime

dirty deeds done dirt cheap, dirty deeds done dirt cheap, dirty deeds done dirt cheap dirty deeds and they're done dirt cheap dirty deeds and they're done dirt cheap

you're got trouble in your life of love you got a broken heart he's double dealing with your best friend that's where the teardrops start pick up the phone, I’m here alone or make a social call come right in forget about him we'll have ourselves a ball

dirty deeds done dirt cheap, dirty deeds done dirt cheap, dirty deeds done dirt cheap dirty deeds and they're done dirt cheap dirty deeds and they're done dirt cheap

if you got a lady and you want her gone but you ain't got the guts she keeps nagging at you night and day enough to drive you nuts pick up the phone leave her alone it's time you made a stand for a fee I’m happy to be your back door man

dirty deeds and they're done dirt cheap, dirty deeds and they're done dirt cheap dirty deeds and they're done dirt cheap, dirty deeds and they're done dirt cheap

concrete shoes, cyanide, T.N.T. done dirt cheap neck ties, contracts, high voltage done dirt cheap dirty deeds, done dirt cheap, dirty deeds, done dirt cheap dirty deeds do anything you want me to done dirt cheap dirty deeds dirty deeds done dirt cheap

First verse talking to a girl who is having sex with her principal Second verse talking to a girl whose guy is cheating on her Third verse talking to a guy whose girl is a bitch

Sex is Bon's solution to all of these. As with every AC/DC song it is about sex and it is full of double entendres to make it sound like it might not be about sex. The "back door man" thing that everyone keeps getting hung up on is he's offering to take the girl off the guy's hands by having sex with her. He will be the one exiting the back door (actual door to the house) when the other guy is entering the front door. This is also a double entendre for anal sex. Bon knew this and put it like that for a reason. The phone number is also supposed to be a double entendre. It is the standard measurements of the "perfect woman".
