Official Bodily Function Euphamisms
Everyone knows what you mean when you go into a bathroom and declare that you are "going #1" or "going #2". I kind of like it; it's not terribly crass and it comes in handy when you only have one small bathroom and you have to decide who gets to go first after a long car ride (#1 obviously). But I always thought that it was an overly cute way of referring to urine and feces.
Until my building installed new two-way handles on it's toilets because we are in a drought and have to conserve water. The sign gives careful instructions that you should pull the handle "Up for #1" and "Down for #2", "depending on your needs." That's right; I shit you not. The official instructions for peeing and popping are "#1" and "#2".
