So over the course of my commute, I see many interesting things. Some make me go, "ahhhh" or even "awwwwww". Others make me go, "oooOOOhHHHH!" Still others, make me go, "hmmmmm?!???!?". I'd say I have more "hmmmm??!?!?!?" moments than anything else.
Anyway, to the point. Have you ever noticed how a bird you startle while riding has a tendency to take a crap at the instant it lifts off from the ground? Is this some sort of evolutionary phenomenon, whereby the brain isn't tasked to control bowel movements, as BM's are triggered by the bird's instinctual motive to take flight when it senses danger?
and yeah, I'm serious. I thought it more interesting to discuss than to google.
