RIP, John Callahan

I saw that John Callahan had passed away in the Style section of the Washington Post today. There's a great article about him. I was first introduced to him from a book my Dad had brought home from work. It was his bio, and one of his cartoons was on the front - a picture of an overturned wheelchair, with some tracks leading off into the distance, and the title - Don't Worry, He Won't Get Far on Foot Amazon appears to still have them in stock - if you're interested in learning more.
