Ever wonder how this trend got started?
A man is at work one day when he notices that his co-worker is wearing an earring.
The man knows his co-worker to be a normally conservative fellow and is curious about his sudden change in fashion sense.
The man walks up to him and says, "I didn't know you were into earrings."

"Don't make it such a big deal, it's only an earring," he replies sheepishly.

His friend falls silent for a few minutes, but then his curiosity prods him to ask,
"So, how long have you been wearing one?"

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

I heard that as well but the subject was girls panties. You should contribute to our ongoing site of "No New Jokes"on this forum;you're bound to know a few.

Version I heard is two buddies are getting dressed in the locker room after tennis and one puts on pantyhose.

"Jim, how long have you been wearing pantyhose?"

"Ever since my wife found a pair under the front seat of the car!"
