Cubby blue

Three members of the Blue Man Group were on the field during the Cubs’ early batting practice session, talking to Ryan Theriot, Micah Hoffpauir and some of the other players. They posed for photos. If you haven’t seen the show, the men are bald, they wear black jackets and pants, and their faces and hands are all bright blue. It was a weird sight.
