Why So Serious?

I have this strange feeling that people take me too seriously. I could have bigger issues, but this one tends to bother me. I would estimate that 65-75% of everything I say is sarcasm.
Problem is - I don't think it translates as sarcasm to people other than my close friends. My close friends know how sarcastic I am.
In all truth, I maybe sorta can get irritated easily, but it doesn't last. And I also try not to show it. So I want to know why everyone takes me so seriously.

Maybe I should start dressing up as the joker and proclaim "Why so serious?!"

Then maybe people would laugh with me. I would like some feedback on this. If anyone reads this. Generally I'm a pretty laid back, carefree person. I don't like people thinking I'm an uptight, temperamental psycho. 

I can be. On occasions. Rare occasions. But we all have our moments. 

On another note - It's finals week. I only have two finals. One in Concepts of MIS and one in Discrete Math. I need to study for both. But have so far been unsuccessful. I think at this point in the semester there is a relatively long list of things that I would rather do than study. Since I have the handy dandy tool of a numbering system, I'll just go ahead and make that list

1. Clean - If I am trying to avoid studying, I will clean my room, the kitchen, the bathroom.. anything. Do laundry. Anything but study.
2. Cook - I think a lot of people eat when they are procrastinating something, but I don't just heat up a hot pocket or throw a frozen pizza in the oven. I'll make some delicious cupcakes or a full blown meal. Much more time consuming.
3. Movie - This one is kind of a given. This one throws me off though. Because I'll tell myself that I'll study while I watch the movie. Yeah, that never happens. 
4. Read - My Kindle has drastically forced me to decrease my study time this semester. 
5. Work out - This isn't necessarily a bad thing. A little exercise is good for a person. Especially since I will be leaving for Florida in two weeks. That bikini isn't going to look good on its own!
6. Blog - If I can somehow put the millions of thoughts into words, I will write them down. Here in my lovely blog. Usually I can't put them together in a form that makes sense to the average human being, resulting in a post much like this one.

Anyways. I'm going to try and study. Yeah, that was a lie. I'm going to watch The Holiday and dream of a romance like the one Jude Law and Cameron Diaz have in that movie. (Great movie, by the way) 

Peace, Love, and Snowflakes
