NO!!! The dirtiest part of your body isn't the thumb but it's not what you think it is either because it's not the butt! I repeat, it is NOT the butt!
It's the belly button!!!
What's so bad about the belly button? I think the main issue is, for being such a prominent and easily accessible body part, people rarely seem to wash it with the same care they use for other areas of the body.
Ok, this might be disguting, but you gotta try it!
Put your finger in your belly button, swirl it around..........now smell it!
I know disgusting right? Now you'll learn to clean that nasty smelling thing better.
