Let the Good Times Roll by Guy Kawasaki: "Always use the toilet in an airplane after a woman. This is getting a little vertical, or horizontal, depending on how you want to look at it. Simply put, men pee on the seat. Women don't. And if a woman follows a man who peed on the seat, then she will clean it up before she sits down. If you sit down after her, you're good to go--so to speak."

good advice for my sister and dtc!
