Well, the Wish You Were Here jersey is not available yet. Mid-January they say. But I got a Dark Side of the Moon jersey for Christmas. I wore it to my club's weekly winter trainer ride last night. When I peeled it off I discovered an "Easter egg."
Inside one of the three rear pockets is printed, "The lunatic is on the grass." The center pocket says, "The lunatic is in the hall." The last pocket, naturally says, "The lunatic is in my head."
