You know, I always imagine what a voyeuristic alien society would be saying about us. Imagine that we've been under some manner of long term observation by these entities.
I don't think we could fault them if they concluded that Earth was essentially one big exercise in developing the most efficient ways of making penises grow.
In a similar vein (sorry), I've often thought that after our civilization collapses and the archeologists of the future dig through our cities they'll come to the conclusion that we are all worshipers of the poo. After all, likely the most durable object in our homes is the toilet, all homes have them, some have SEVERAL and they have their own little area. 15,000 years from now in the crumbling remains of our cities, porcelain fixtures will probably still be around.
As for the artificial peens.. I hope it doesn't actually work. We're already way to focused on our peens as it is. Overly obsessed about the size and shape of them. It reminds me of a line from a TV show: Cat: What was it like being a hamster?
Lister: It was better than being a chicken. Have you seen the size of an egg? Seen the size of a chicken's bum? That's what all the clucking was about. I was trying to say in chicken-talk "for God's sake, give me an epidural!"
If men were in charge of peen size we'd all probably die from blood loss in the brain the moment we went into puberty.
