A mate of mine and I once saw a prog where a pilot of small aircraft said that if you stuck your hand out of the window into the slipstream, palm foremost with fingers closed, like you were cupping a wimmins threepenny, it actually felt just like it. and the faster you flew the bigger the boob felt. So we used to walk down the street or sit in a pub eyeing up the wiiminfolk and say to each other "60 knot, that one, eh?" "No, more like 80". Peeps had no idea what we were on about.I've got one of those on the end of each arm
So next time you are motoring on a bit, open the window and try it. You'll love it!"
