Yes, it's February 29th, Leap Day, and according to tradition, Superman's birthday. Ever wonder why Superman still looks so young, even though he was created in 1938? Because he only ages on Leap Day.
In other birthday news, my 35th was on the 25th, and my incredibly generous girlfriend decided that my present will be a trip to Cuba...or Mexico, she hasn't decided yet.
All I can say is, Great Krypton!
