Bottom at the Top

Listen here, smarty pants, you think you know everything, huh? Well, lemme break it down for ya real simple. So, like, a bottom is usually at the bottom, right? But get this: your leg has a bottom where it connects to your body, so it is at the top of your leg. Mind blown, right? That's why it's funny, because it's unexpected. You probably have two of them too, but I bet you don't use them for walking too much.
