I only had a side view of one person, and from what I could read, his shirt had the letters “OT IL”. I thought it was a geek takeoff of the “Got Milk?” ad campaign, this one for cool people who use .NET and compile to MSIL (Microsoft Intermediate Language).
When the “OT IL” fellow stood up a bit later, I could read the entire message. It was a statement, not a question: “NOT EVIL”.
Heh. I think “GOT MSIL?” is much cooler.
