Earrings

A man is at work one day when he notices that his co-worker is wearing an earring. 

This man knows his co-worker to be a normally conservative fellow, and is curious about his sudden change in fashion.

The man walks up to him and says, "I didn't know you were into earrings." 

"Don't make 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 say, 

"So, how long have you been wearing one?" 

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