Now it might be that that doesn't exclude emotional exuberation, but somehow I've always read it as doing so. So it struck me as funny when I got behind a car the other day whose spare tire cover read
OM WOO
Hmm. "Ommmmmmm. Woo!!" Seems incongruous, no? :)
It's another one of those "letters missing" bits, and the car dealer the guy bought his car from's called Tom Wood. But it's much more interesting reading it the way it appears on the car :)
