Drive around anywhere in Rural America and you will see pick-up trucks with something hanging from the trailer hitch. Called truck nuts, truck testicles, trailer balls, and many other names, these dangling items look like a scrotum containing two 'nads. They are not, however, just ornamental.
Researchers at John Hopkinson University Medical Center and Auto Body Repair have discovered that the big pairs of huevos really are testicles and do produce semen. Dr. Goodwrench of the University said that "we assume that machines have now advanced to the level where they are able to be reproductive with each other. When you see a truck that appears to have rear ended and pulled up onto another, they are possibly just mating."
Scientist have analyzed the liquid that drips from some car tailpipes and find that it is very similar to human vaginal secretions.
"We are seeing something new in the evolution of the automobile. We have tagged a few trucks and are watching their relations with some chick mobiles (cars like the Porsche, the mini-van, and the new Volkswagon Beetle) to see what kind of offspring are produced."
"Everyone knows where babys come from, but we now may have discovered where Tonka trucks come from."
