Two funny comics and one serious one.
One of my all-time favorites from the Perry Bible Fellowship (click on the comic to view it on its original page):
A favorite from Wondermark (again, click on the image to view the comic on its original page):
Finally, a comic written by Neil Gaiman, illustrated by Jouni Koponen. This one is a multi-page affair, so you’ll need to click on this link to check it out. It is entitled Babycakes.
