Gender Assignment For Your Vehicle?

So there I was, driving down the highway, when I noticed something hanging from underneath the pick-up truck in front of me. I got closer to see what it was and, low and behold, it was a set of nuts! Yep…testicles, balls, the two boys, family jewels, or whatever you choose to call them; this truck had a pair. I’m not sure how widespread this phenomenon is, but I have spotted a few other vehicles that are apparently “males”. I consider myself a bit of a northern redneck because I was born and raised in a rural northeastern town, where hunting and fishing was the major source of entertainment and a nice pickup truck was the vehicle of choice. So I understand the tendency to customize a vehicle especially with something functional (ex. bug deflector or mud tires) or with an emblem of your quarry or conservation group of choice. But, I just can’t see the sense of placing a replication of, arguably the least attractive part of the male anatomy, on one’s vehicle.
Now, two questions come to mind.
1. How did something like this find its way to a retailer?
I envision a brainstorming session at a major truck accessory supplier. All the brightest market research analysts are present and they lock themselves in a room determined to find the next big trend in vehicle accessories. After hours of debating, Bob stands up and says “I’ve got it. We’ll make rubberized testicles that can be attached to any vehicle to give it the manly touch.” The room breaks out in applause and Bob is awarded the employee of the month and gets a nice fat $15,000 bonus, for thinking “outside the box” or maybe “inside the pants” in this case.
2. The next question, what compels someone to actually spend the time and money to utilize this accessory?
Again, I envision a man named Cooter, who just spent thousands of dollars buying every truck accessory offered in a J.C. Whitney catalog. Cooter drives his highly modified “pride and joy” over to his friend Bubba’s house to show off his new ride. Bubba says “Truck looks good, it’s just not manly enough for my tastes, and it’s missing something. Cooter, I think your truck could use some balls.” And the rest, as they say, is history.
