What is the most random thing you've seen today?

I was out on my dorm's stoop smoking a cigarette and this 60-year-old guy is walking by. We say what's up, and then he stops, and says 'Do you guys ever stop?' After that, we had no clue what he was talking about, but he talked about stopping for something. Then, we asked if he took any classes. He said no, that he only took pictures, offered to take pictures of us, and said he was only there to take a picture of this detailed eye in the art center, to show people what it's like to be 60 years old. I thought he was on acid or something. What the fuck.
