Does your body do random, weird stuff to you? Or do you have weird habits that you tend to do which other people don't?

I hiccup when I get full. I don't know if that's normal, but it happens! Not constant hiccups, just, like, one or two. XD And if I get real hiccups, I always get them twice in the same day. Usually one set in the morning, then later at night. XD Makes no sense.
