Okay, so this has NOTHING to do with my family but I get a kick out of their thinking! Just leave it to the Aussies!

An ad campaign aimed at preventing traffic deaths in Australia mocks the manhood of speed-obsessed drivers by having women waggle a little finger at them.

The pinky gesture, meant to symbolize a small penis, hits male drivers where their sense of humor stops: below the belt.

The new ads show one young driver at a traffic light revving his engine and burning rubber in front of two young women. As the car speeds off, the women exchange a knowing glance and slowly wave their little finger.

The ads' tagline? "Speed: No one thinks big of you."
