A man's gotta do what a man's gotta do......

A man notices that his coworker is wearing an earring.

This man knows his coworker to be a normally conservative fellow, and is curious about his sudden change in "fashion sense." So, he says, "I didn't know you were into earrings."

"Don't make a big deal of it, it's only an earring," the coworker replies peevishly. His friend falls silent for a few minutes, but then his curiosity prods him to say, "So, how long have you been wearing one?"

"Ever since my wife found it in my truck."

I always wondered how this trend got started, and now I know.
