i don't have that many but i have a friend that does
he cuts out pictures of dead people in obituaries and puts them in his wallet
Give me his name and address so I know not to go near his whereabouts.
I crack my fingers in certain ways. If I find that one or more fingers don't audibly crack, then I'll just keep messing with the finger until it cracks. I always grab my middle and ring fingers in the opposing fists and bend them backwards until both crack. I then use the opposing thumbs with my other opposing fingers against the back of the hand to push my pinkie downwards until it cracks. I then put a thumb on top of its neighboring pointer finger and push it downwards to crack. I then make a simple fist with my thumb through the center and clench until my thumb cracks.
I also chew on parts of exterior clothing that is hard and too close to my mouth. That includes laces, zippers, and snaps.
When I'm sitting down, I frequently find myself kicking my shoes off to the point that only my toes are still touching the sole.
Whenever someone talks to me, I always look at their mouth.
When playing video games, I always adapt to a routine over time, sometimes to the point of being obsessive. For example, on Gran Turismo 6 (PS3), I always have to drive on Circuit de la Sarthe 2013 for 8 laps with clear weather and begin a race at exactly 18:30 hours game time. I also can't look at my opponent cars because I like to find out what they are when I'm overtaking them. This specific race can take anywhere between 25 and 40 minutes, and I've done it as many as 30 times in just one week's time.
