It is just a joke---.
"Why some men wear earrings"
A farmer was at a diner one day having lunch when he noticed an old friend. What really caught his attention was that this friend was wearing an earring.
The farmer knew his old buddy to be a fairly conservative fellow, and was curious about his sudden change in "fashion sense."
The farmer walked up to him and said, "I didn't know you were into earrings."
"Don't make such a big deal, it's only an earring," the fellow replied sheepishly.
The farmer was silent for a few minutes, but then his curiosity got the best of him and he asked "So, how long have you been wearing one?"
"Ever since my wife found it in my truck," the man replied.
