I am not good at telling a joke, or a display of humor in which words are used to make people laugh. 
That reminds me of Lieutenant Commander Data from Star Trek the Next Generation.
I don't know about him. What I do know is that jokes normally take the form of a story, and ends in a punch line.
Data is a robot and is incapable of understanding comedy. So he spends much of that series hilariously trying to understand comedy with very little success.
Oh, yes it does sound like me. Interestingly, not all humor is a joke, but all jokes are a form of humor.
Not all jokes are funny though, that's for sure.
Definitely not. Dark humor is definitely not my thing.
I sometimes engage in a bit of dark humor. It comes with the territory of being a snarky person.
