toilet stalls

As a male I probably spend more time than the average person in men's bathrooms. (According to 2008 world demographic data the average person is about 50.5% male and 49.5% female, and I most likely spend more time in men's bathrooms than a hermaphrodite that is just slightly more male than female. Also, I am a bit creeped out by men's bathrooms, so I will admit that I put toilet paper over the seat before I sit down, if there aren't any paper covers to use.) Typically, bathroom stalls don't make for wholesome reading, but I will admit that occasionally I get bored (there's really not much else to do) and will read what's on the walls of the stall. Once in a blue moon the stall walls actually have something funny/interesting. Often there are long drawn out strings of bathroom conversations between immature idiots. Recently I saw the following written in two different handwritings (I think it's pretty clear what was written by each person).

FECES <- mouse babies?

I have no idea what this means, but it made me laugh. Given the extra time on my hands, I thought about it and I think that maybe the second writer was thinking that "feces" is an amalgamation of the fake plural "meese" for mice and the word "fetus". I probably gave it too much thought, but it made me laugh nonetheless. I bet it's weird when people laugh from bathroom stalls....
