In college, I had an English professor who always brought an unopened Diet Pepsi to class. Without fail, he would spend a good couple minutes wiping the can's rim until it passed his inspection and was suitable to open.
One day, without prompting, he casually uttered these words:
"Somewhere, somehow, a sheep may have sat on this can. You'll never know."
Because of this one man, I can never drink a canned beverage without picturing a sheep doing very bad things to an innocent aluminum can.
