Lubrication. That's a funny sounding word. I don't know why, but it just is. It's also the correct answer you need to select in order to get this. I actually had a friend who worked at Bosch for a while. Unfortunately, I don't have a funny story to go along with that little tidbit. Maybe I should make one up, involving a monkey, a lavalamp, and a box of Rolaids. Woo hoo, now I have something to keep myself entertained by on the flight home in a few days!
