This SO reminds me of a SaTC episode, Miranda was complaining about all the construction workers hooting and hollering at her on the street. I think Carrie reminded her that she should be more afraid of when they won't. The last scene, Miranda is walking along and gets all these obscene gestures and catcalls, she marches up to one of them, says "Let's go, lets do the nasty", he looks shocked and says "Geez lady, I'm married". Miranda walks away and then smiles when another crew catcalls.
They just do it cause they know they can and nothing ever will happen.
