My co-worker says that dry humor is my hidden talent

That wasn't funny.😐

I wasn't familiar with that comedian so I watched some YouTube videos of a couple of his stand up routines. He's funny! But to answer your question, no I don't do impromptu stand up comedy routines at work.

Usually my seriousness is construed as humor. It's hard to explain. For example, one of my coworkers recently changed her appearance. For four weeks she had the same style. Her hair is a very short Afo. Apparently she purchased 3 different wigs and alternates from wearing the wigs or her real hair. When she wears the long wigs (one is blonde), she wears tight fighting clothing with low cut tops.

So after seeing her wear the third wig, it inspired me to want to buy a wig too. So I stopped by her desk and said, "I'm going to need for you to stop wearing different wigs because it's making me want to compete with you"
And she and a couple of other coworkers started laughing.

I was very serious though and meant what I said. But they thought I was making a joke. So it's situations like that that is how my humor works.
