This is an interesting thread. Some have been mentioned before.
I take the second/third one of things - second game off the shelf, shirt off the rack, etc.
Use my blinker (heh).
I take tons of napkins/ketchup packets/etc from fast food places.
At Chick-fil-a, I eat the fries first and then the nuggets. Everytime. This is only with Chick-fil-A and is a leftover from when I used to get kid's meals.
When I eat a burger or something where I have to add a condiment (ketchup, mustard, taco sauce, etc...), I will add it as I eat a bite. Instead of spreading it on the entire sandwich, I put some on the next area I eat.
Always sleep under a blanket and with a fan on.
Will not enter a store if I'm the only on there. This is especially common at malls. I HATE
going to Hot Topic alone. I usually need someone with me to shake this paranoia off.
I like to do distance running. This isn't all that unusual, but at night (when it's much
cooler, a luxury I can't really afford in Texas until after 11PM), I will go to the local golf
course, remove my clothing, and run naked (but with shoes on) for a long time. It's quite
refreshing and eerie. The golf course, being clear with small rolling hills, and under the
shine of lunar waves, creates a very "otherworldy" feeling. Like being on another planet -
dark, smooth, rolling.
To go along with this, if I'm home alone, naked-ahoy.
Piss outside at all chances to conserve on water.
Hugely OCD about tieing up loose cords. All my controllers, USB cords, computer cords, etc etc etc, ALL of it is tied up. I order 75 foot rolls of cable ties from lanshack.com every few
months. I even get excited at the prospect of tieing up new cords (like a new
controller, etc). Heh, I guess with the advent of wireless controllers, I won't be able to do
that much longer.
Very obsessive about vacuuming. Will sometimes do it several times daily.
I do "clock equations." For example: 3:21. I think "3 - 2 = 1." I am trying to determine a
way for all times of the day to have an equation associated with them. I'm also trying to
determine which hour/minute combination offers the greatest flexibility in terms of a group of ten. In other words, from 12:40 - 12:49, does this have more possible equations than 1:30 - 1:39?
When I get something expensive (new computer, monitor, etc) or something that I particularly care about (MX1000 mouse, etc), I will take massive steps to ensure all it's information is preserved. What I mean is that I will scan receipts, preserve all the bags/manuals/twisty ties/original packaging, create text files full of all the numbers I find (serial, order #, etc). I print out receipts as well, and take screenshots of them and keep them all in a folder. When I'm done compiling all of this information, I burn it to a disc and store it away safely. After doing tech support for so long, and seeing serial numbers rub off on components, and knowing that this can sometimes be used to verify a warranty, I decided I won't take the chance. Sometimes I'll put clear packing tape over numbers to avoid them being rubbed off over time.
To go along with that, when I send in a mail in rebate, I scan EVERYTHING in both small and
fine formats. 20+ megabyte file from a Best Buy receipt? Yep. F*ckers aren't going to deny me a rebate...
As I cook, I clean the entire kitchen.
To clean my room, I need the tv on with something that I'd like to watch, but have seen so many times I don't care. For example, Futurama DVDs.
When I change lanes, I signal BEFORE switching lanes, as opposed to doing it all at once like a bad driver. "Bad" can also be described as "normal" in this case.
At work, I clean the keyboard before I use it, especially since we are currently sharing desks. Bleh.
I carry floss and q-tips in my car. Just in case. I hate the feeling of stuff in my teeth or an itchy ear.
Occassionally my right shoulder blade will start having intense pain. And for some reason,
whenever this happens, I start laughing hysterically. People are very confused and scared by this. I'll do this with other types of pain except headaches and stomachaches.
