Paperback: 120 pages
Publisher: Dark Horse Comics,U.S. (30 May 2008)
Category(ies): Webcomic compilation
The fifth compilation, following after Birds Are Weird. If you've been collecting these, then you'll be getting exactly what you expected. If not, well, there's no continuity to worry about, so you could start with this one as easily as with the first volume.
So, two of their Penny Arcade strips per page (except when there's only one), with short commentaries on each at the bottom of the page. There's also a rather fine story at the end, The Last Christmas, wherein great Lord Cthulhu rampages delightfully. Otherwise, it's yet another collection.
