When I was about 17ish me and buddy were walking up my parents driveway. My old man was cleaning and detailing the inside of his truck. All of a sudden a pigeon flew in the driver door, perched on the steering wheel and dropped a big bird deuce all over it. One of the funniest things I've ever witnessed. 20 years later and we still talk about it.
I'm reminded of facetiously asking a coworker, "Do pigeons realize how stupid they look walking around with their head bobbing like that?" Her response was, "They cannot help it."
