While we're on the topic of phallic contrast/comparison (mine's bigger than yours, and I'll show you just HOW MUCH and WHY!), I figured it would be relevant to bring up the American countryside.
Seriously, go for a drive out in the country. What do you see? Nestled amongst greenery and fertile nature is a bevy of huge, shaft-like buildings topped by a domes that contain stuff necessary for the sustaining of life on earth.
I'll be blunt, silos are like huge penises (in both form and function) looming on the horizon.
Yes, we decorate our country well.
Needless to say, I agree with FunGuy. I daresay we think with certain bits of our anatomy not located atop our shoulders.
Ugh. Now I don't know if I want to smoke a cigar this weekend...
