Valve has announced that The Orange Box will come with another surprise goodie - a music single from a chap called Jonathan Coulton.
Described as a computer programmer "turned modern day rock star", Coulton produced a song co-authored by Valve folks and fans who specifically solicited him to do one.
"I am delighted the Valve design team selected me to help make the surprise single a success," Coulton said. "If it's not every geek's dream to be immortalised in a video game, it was mine."
And if that's not enough to keep you busy for five minutes on a Friday morning, why not check out some of our Orange Box coverage? It's due out on Steam from 10th October, and at retail for PC and 360 on 12th October.
