I'm kind of embarrassed, today at the bookstore it was really slow so I was just killing time with a permanent marker...and some of it soaked through onto the counter! I couldn't get it off, so I just covered it with a check acceptance policy poster and hoped nobody will notice until Monday when I can come back with some nail polish remover. I can't believe I did that.
I heard a riddle though today that I thought was pretty good:
A hundred feet in the air, it lies flat on the ground. What is it?
A dead centipede!
