Great webcomic... NSFA (Not suitable for anyone)
Edible Dirt
I hate to admit that I find this comic funny. Some of them are downright hilarious. But I'll never admit that. The linked comic is probably OK to look at while at work... but you're on your own if you explore the archive. If someone asks what you're laughing at... I recommend telling them the cannibal joke... "Did you hear about the cannibal who passed his brother in the woods?"
I will admit that I laughed my ass off at the one I linked to. But the one with "Dude... You're leaking..." That's not funny. Not remotely funny. Nope.
