Yep, Scandal Sheet (link fixed) is the work of our very own Chef Troy.
The other webcomics featured in my toolbar are Sluggy Freelance (which has already been mentioned), User Friendly (a geek comedy strip), and Adventurers (a console RPG, only it’s a webcomic).

It’s 18th century author, Sir Walter Scott! And this time, he has a gun!

Hey! Nobody’s mentioned Crap I Drew On My Lunch Break by our very own Jinwicked.
First of all, jinwicked is awesome.
Second of all, there’s the rarely updated Pixel Pals, which makes me giggle like a schoolgirl.
Cfrh: Hallucinatory sort of college-drama-mystery-supernatural adventure strip. Very well written (although English isn’t the author’s first language). Sort of like Buffy, but madder and with absolute disregard for the staus quo.
10K Commotion: A sexy Hawiian sports drama comic. It’s ostensibly ‘about’ DDR, but only in the same sort way that most sports dramas are ‘about’ a sport… it’s really all about the characters. The sexy, sexy, characters. 
Narbonic: The harrowing tale of one man’s descent into madness and morally disastrous actions, his downfall at the hands of a mad and unattainble woman. But funnier than it sounds. And cuter! And alarming more literate than most web (or print) strips. It really deserves to be better known that it is. Unfortunately, currently only available on a subscription site – only the current day’s strip and a small sample are readable for free. Tragic.
I’m surprised no one’s mentioned Get Your War On yet.

Penny Arcade and Achewood are wonderful, I always find them entertaining.
My other favorite is Red Meat, which is funny, sick and disturbing all wrapped up into one twisted comic.
Demian5’s When I Am King. Just a great, great story.
Derek Kirk Kim’s Small Stories . Lots of stuff on his site worth looking at.
Tom Beland’s simply terrific True Story, Swear To God, which I first encountered back in 1999 on my old 56K dial-up modem back when we used to post on Wizardworld.com’s old message board – and I still read every strip he had on the site. It, along with PvP and Small Stories, are the few strips I enjoy that made the transition from the internet to print.
Tatsuya Ishida’s Sinfest. Gets a little obvious in its gross out humor, but the artwork’s not bad at all.
I know Scott Plaid already mentioned it, in a way, but I’d like to make the recommendation explicit: Girly is really great, in a warmnfuzzy kind of way. It’s a little - uh - much with the innuendo, but its heart is in the right place.
Its predecessor cutewendy … not so great. But I can’t recommend Girly enough.
