I'm with uncleb, I didn't pay much attention to it until the lady entered my life. She likes it over, I'm an under kind of guy.
Speaking of the Simpsons, watching them now and Bart just took the elephant (soon to be named Stampy) over the $.
Homer: "Bart! With $10,000 we'd be millionaires. We could buy important things like... Love."
OK back to the question. It seems to tear off better if coming from under.
Oh, and I'm a wad-er.
