Mark Twain said this quote

I followed the other Experiment around, yesterday afternoon, at a distance, to see what it might be for, if I could. But I was not able to make [it] out. I think it is a man. I had never seen a man, but it looked like one, and I feel sure that that is what it is. I realize that I feel more curiosity about it than about any of the other reptiles. If it is a reptile, and I suppose it is; for it has frowzy hair and blue eyes, and looks like a reptile. It has no hips; it tapers like a carrot; when it stands, it spreads itself apart like a derrick; so I think it is a reptile, though it may be architecture.
