The victim, blissfully unaware of this recent addition of 'artwork', drove home, parked up, and still didn't notice the grime-etched phallus. It was not till some time later that his mother approached him and announced, 'Someone's drawn an alien on your car'!
First thing that struck me was, 'poor woman, I wonder how long it's been since she saw a naked male!'. Though it also occurred, perhaps there's some truth in this woman's much ridiculed report of many years ago, when, nine months' prior to her son's birth, she claimed to be abducted by aliens and subjected to a vaginal probe...
My preferred hypothesis is simply that the artist was incompetent and had no idea of proportion, making the head of the penis enormously large, thus accounting for the mistaken identity on the part of the woman. Still, you can't help but smile, and think not so much of 'ET phone home', as 'ET rammed home'!
No apologies to those of you who groaned at this last remark. Have a nice day.
