Why do I do weird things?

Yeah...why do I do weird things? I know I'm intelligent. I have an I.Q. of 90 so I know I'm not retarted. Is their a cure for weirdness or is this something that I'll have to learn to live with? I'm in my early 20's and I boogie down to Miley Cyrus tunes and my friends think I'm nuts. That's only the tip of the iceberg.
