Here's a financial tip for you. If you ever see a guy like this on the train, get off on the same spot and follow him. He just may lead you to a pot of gold. Don't think he won't be armed though. After centuries of having their gold stolen, I'm pretty sure that most leprechauns are strapped by now. Of course, we know this guy isn't a real leprechaun due to the fact that he's 6'6", 250 pounds. That's not your typical leprechaun size.
You have to hope that you see something like this on or near St. Patrick's Day. If not, then you're dealing with a crazy person. You're probably dealing with a crazy person regardless. I'm thinking this guy should have chosen a different costume. One that is more in tune with his body size.
