It's really a long story, but do you remember the insurrection at the capitol building from a few months ago? Okay, by a strange accident (don't ask, really), I had been locked inside a trick cabinet in the office of US senator Tammy Baldwin several days before. I had food and water to survive, but it took me a few days to pick the lock. Once I picked it, I was afraid to come out, because, obviously, that would surprise Baldwin and her aides, and I didn't want to cause any trouble. However, when everyone was evacuated during the insurrection, I saw my chance to escape. I climbed out of the cabinet and was about to leave, but something caught my eye. On the floor of the office were arranged, in a row, 26 alphabetized stacks of paper. Each stack of paper was exactly 500 sheets. I picked up the fourth stack of paper from the left. What could I call this stack of paper? I found myself getting veeerrry sleeeeepy contemplating what to call it.
