As someone who has supposedly used the chat up line ‘shall we do it then’ while drunk (though I personally don’t remember that) I thought this old Victoria Wood song was amusing, seeing as she sings about a woman using the line ‘Let’s do it’ – which is close. I remember watching this when I was a kid, which was a long time ago. The line ‘come and melt the buttons on me flameproof nightie’ is a classic.
