Highly Irregular!

I found a new webcomic that is good enough for regular following. Irregular Webcomic! by a geeky and extremely knowledgeable Australian guy whose name I don't know is a genuine laugh riot. It does mostly theme-based comics, built from Lego, RPG figures, and real-life photos of the author and sometimes some other people. Many themes directly draw inspiration from real-life fictional work, people or incidents, but that fact is not always admitted. I don't blame the guy, given the possibility of his humour being misinterpreted.
Two additional good things about this comic: it is PG-rated, and it raises money for the Jane Goodall Institute (he has a theme on Jane Goodall too). So go read!

Edit: David. His name is David.
Edit 2: Hah! Found it. David Morgan-Mar. I didn't want to research, and was waiting for another mention of his name as I flipped (clicked) through the archives.
Edit 3: The comic's been discontinued last year. But hey, there's a whole huge archive to read.

He fell on a log and found a root...

... a square root.
I fell on a link and found an awesome math webcomic Spiked Math. It's a comic, in colour, where all the jokes are based on mathematics. Being more topical, it is tougher to do (an understand) than general humour, but nevertheless great fun. The site comes with a commenting system akin to blogs, which often adds to the fun and results in follow-up jokes, and many non-math people can enjoy the comics because of others explaining it to them in the comments. The artist is Mike, who's own favourite webcomic is xkcd. He has a ranking system of other webcomics, and his list is a valuable source of more funny comics. He does his comics with MS-Paint: the art is not exceptional, but the jokes surely are.
Speaking of webcomics, I found several sites that regularly explain xkcd. Since there are several, you'd better Google 'explain xkcd'. There are similar ones for several other webcomics too. I'm serious, there really are. Really. I'm not being irrational here. I'm not pi.

Candorville, Perry Bible Fellowship, Questionable Content;
The last two I came to know of from the great xkcd; first one through the famous The "Blog" Of "Unnecessary" "Quotation" Marks, when its author linked to a related comic on it.

Awesome Webcomic Site!

http://xkcd.com -- the artist is extremely witty, and the drawings are evidently done very skillfully. Or else how does just the outline of a head convey an expression? It's hilarious, fabulous, tri-weekly, and will leave you in splits.
Warning: Not for kids.
