Just a theory ok, just a theory. At university I used to know a girl who was convinced she could tell, by the shape of someone’s lips, how often they showered. Of course we never got to find out if her theory was correct as I wasn’t in the business of asking people how much they showered. Whatever lip shape, the shower question just didn’t come up. However, why let science get in the way of graphs? As my pals at humor blogs say, the plooptionary is just like a “math lesson gone wrong”. I think the theory below will stand even the most scientific scrutiny. Please feel free to exchange ‘make-up’ for ‘aftershave’ depending on your sensibilities!
