Whenever I see a Kia Soul in white or cream color, I sing the Darth Vader tune (dun, dun, dun, duhDAHdun, duhDAHduuuuuuun!!), because I think they look like storm trooper helmets. Yet, I never do it when I see a black one. I got my H doing it now, too. It's like out of no where.
If I wake up at, say, 7:47, I will wait 3 minutes to get out of bed, I MUST get out of bed at an evened numbered time. Same with leaving the house, or starting anything really. 
I won't eat chicken sandwiches pretty much anywhere for fear of eating non-white meat or biting into a nerve or something. If I eat pasta, or a salad with chicken, I inspect every piece. 
I really like Hall & Oats.
Now, what weird things do YOU do? I have so many more, I will think about them and post more later.
