classifying humor: ... interesting?

*I started writing this post a couple days ago, but my internet went out and I lost the whole thing. So this is a reconstruction of that same info and is related to my secret crush post :)

After my last post I started thinking about the last time I talked to this little crush of mine. (And for clarification, this crush IS a different person than the married, pretend crush…just fyi.) This led me to start talking to the friend through whom I know this crush. And the conversation that followed pretty much exemplifies the joking manner I mentioned that always comes up between me and my friends. So I thought I'd share this conversation with you for two reasons: 1) to show a firsthand example of the joking manner I explained and 2) to ask you to define the type of humor this is. I was trying to figure it out because, I admit, at times it's really weird. So any thoughts just may help shed some light. Enjoy.

Karianne: Hey! So...do you at all remember who I had one of my crazy crushes on a while ago...like where I get obsessed and weird?

*Bob: Are you refering to *Mr. X.

Karianne: Lol wow Bob, you are pretty good....Yes I was. Lol facebook said he and his girlfriend broke up and I was reminded of all that once again...

Bob: Did they break up? That's sad. Mr. X's sister was happy about their relationship.

Karianne: Yea, according to facebook they did. Yes, sad day...but now maybe there's room for me! Um, I mean, just kidding.

Karianne: P.S. Do you think Mr. X's sister would be happy about our (meaning me and Mr. X) relationship?

Bob: Probably. I think she was happy for the fact that he was in a serious relationship.

Karianne: OK, whew....I do hope she likes me too once Mr. X and I start dating. :) Do you ever see him by the way?

Bob: Nope. Never.

Karianne: Darn it. You are useless to me, Bob. Simply Useless. . . . OK I really need to stop this madness. So fyi, I do hope you know I'm not serious. Well, about the methods and drama. I totally wouldn't mind dating the kid.

Bob: I think you are sane. No worries.

Karianne: Good. I think you are too! So do you know how you would categorize this type of humor? I can't figure it out..

Bob: Interesting?
