I typically use the two minutes spent brushing my teeth walking around the house, petting the cat, and marveling at how someone I work with has over 500 friends on Facebook. Another of my colleagues recommended her as a friend, but wouldn't I be just a drop in the bucket to such greatness?
Sometimes at work, I'll want to itch my ass, but first have to look around to make sure no one is looking my way (as if they don't do the same thing). Walking around the lake when such an urge strikes, I'm tempted to do the same looksie, but am generally like, "Who gives a fuck?!" and just do it already. One can't live their life worried that others are gonna think less of them because they like to "itch" certain body parts.
