#2897: Light Leap Years

[Cueball is sitting at a desk with a laptop on it and leaning to the back of his office chair, while having his other hand on the laptop. He is looking at Ponytail, who is standing behind him. The text from the laptop screen is shown above it, indicated with a zigzag line.]

Cueball: It took until February, but I finally got all the distances updated!

Ponytail: I really wish we didn't have to do this.
