This is a nod to a comic by an old friend, Robert T. Balder. Before he skyrocketed to fame with "Erfworld" he wrote a brilliant webcomic called "PartiallyClips." Now "PartiallyClips" is written by Tim E. Crist, but when Rob was working on it he occationally would need to pick up extra art for his comic. I did one of those comics. http://partiallyclips.com/2003/07/13/blood-cells/
The format of this comic is the same picture repeated 3 times where the dialogue is funny. I am not as funny as Rob but at the same time this is a nod to his first foray into the medium of webcomics.
