I do all kinds of wierd shit.

  • I always have to be doing something with my hands, when nothing is required of them, I usually twirl a pen around or toss random small objects and catch them. I usually don't even pay attention to myself when I do this, I just do it without thinking.
  • In my free time, I sometimes like measure mundaine objects I'm likely to be carrying with me in the future, such as my wallet or car keys, so I can use them as measuring devices at a later date if I ever need to measure something and don't have a ruler or tape measure or something handy. Also measured and memorized various lengths on my hand for the same reason.
  • I alphabetize things that I have no reason whatsoever to alphabetize, such as my medicine cabinet, the refridgerator, my guitars, my closet, and other such useless things, meanwhile I refuse to alphabetize things which alphabetizing might help with, like my video games, movies, or books. Don't know why, don't even think about it half the time.
  • If I notice somebody staring at me for too long, I'll mentally yell, "STOP READING MY MIND YOU <insert word that would be censored here>!". Hey, you never know...
  • I like rewatching Star trek: The Next Generation episodes and counting the times Data accidentally uses contractions, or catching science and math errors. For example in one episode I caught them saying the surface temperature of a planet they found was about 17 degrees below absolute zero.
  • I have to break everything before I throw it away. Paper must be torn up, plastic must be mangled, cds have to be snapped in half, electronics that no longer function must be smahed... etc. I never throw away anything intact.
  • I block out the lights on my electronics with random crap laying around so they don't annoy me when I'm trying to get to sleep. I usually throw a T-shirt over the shelf with all my gaming consoles on it, if I don't I'll sit there staring at the lights all night.
  • Whenever I wake up in the middle of a dream, I won't actually get out of bed until I imagine an appropriate conclusion for it.
  • I calculate random physics related crap when bored. Like I'll just sit there calculating the ammount of joules in my breakfast, then converting it to megatons and figuring out how many of whatever I'm eating I'd have to eat to consume the energy of the bomb dropped on Hiroshima, or calculating the exact momentum of my car when traffic is moving slow, just random utterly useless crap like that. Just for the fun of it.
I'm sure there's a bunch of other crap I do I'm sure people would consider a wierd habbit, bit that's all that's really coming to mind right now, I'll keep thinking on it.
