I pooped while I was there.
But there's more:
I pooped in the National Archives [it's free admission there]. It was a Sunday. I had just seen the Constitution, the Declaration, the B. of R.s, etc. There were a lot of school groups floating around the building. I had several layers on and a heavy backpack, so it took me some time to set up for my work once I got into the stall. Thereupon, I realized I was one of two people in the bathroom. The other person, probably derived from one of the school groups, said, presumably to himself, that this must be the quietest bathroom in the world. After he left, I felt like his assessment was pretty good. It was a quiet building on a quiet winter Sunday, and there was just me, having a quiet poop.
Pooping in a library bathroom is one of the distinct pleasures in life. Pooping in one of the nation's ur-libraries is thus a sweet thing indeed.
PS - anyone ever call that NFL QB the mocking name of Bathromo?
