I click my tongue really loud whenever I say something really fast, so loud that the entire room jumps whenever it happens (I can replicate this sound at will). I look around at everything, and by everything I mean everything. Even if I've been in an area for hours on end I still look around at everything, I don't know why but I always have this feeling that I'll notice something really cool if I continue to look around. Another noticeable one is when I am standing still I tend to elevate my left foot a few inches off the ground, it doesn't throw off my balance in any way and I don't even notice it. I have a friend who whips out a stopwatch everytime I do it, according to him my record is 23 minutes, (it was very odd I didn't feel like moving) of course he only really stops the clock when I put my foot on the ground for more then a few seconds, it's not as if I stood on one foot for the good part of a half hour.
