Here's a mad cool guest strip by Tyler Sticka. This strip is part of The Book of Substitution storyline, which will pick up right where it left off as soon as The Book of Celebration is done. If anyone else wants to do guest strips for next month, send me an e-mail!

I tried to hold out on Tyler's strip until the guest strips returned, but I just couldn't. It's too cool. This is Tyler's take on Shady Dave, a very minor character who was always lurking in the backgrounds. See if you can find him anywhere, it's like Where's Waldo!
