Tell me all the weird and wonderful things you do and just can't stop.

I'll start:

When something is loading on the computer, for some reason I close my eyes and open them when I think the thing is finished loading. Over time I have become almost unable to watch a full loading screen...

I've never bit my nails but I do bite my knuckles sometimes which is a little weird...

I also do this weird thing with my eyes a lot, where I shake them from side to side really fast that they just look like a blurr to anyone else.

I also like to pee in the toilet as it flushes, lolol.
What about you guys?
