Do you have any weird habits?

I've seen people who smell their ear wax after digging them from their ears. Even heard of some who will sniff their toe jam after cutting their toe nails. When I was young, I liked to taste my dried up mucus after digging my nose. Just to know how it smells and tastes like. Now, I MUST wear my left shoe first before the right one. Interesting yah? How about sharing your weird habits?
