Wait... you think CAD is entertaining ? I used to think that until I discovered it was just wall of texts, the same facial expressions and that the joke (when there is one) is explained in the last panel.
Anyways, if you want good webcomics, here are some:
The Perry Bible Fellowship
<a href="http://pbfcomics.com/">http://pbfcomics.com/</a>
Too bad it stopped being updated, it still has some of the most hilarious comics I have ever seen.
Looking for Group
<a href="http://www.lfgcomic.com/page/1">http://www.lfgcomic.com/page/1</a>
It started like a wow parody webcomic, but it fastly began it's own thing with it's own story. The webcomic in itself is hilarious.
Brawl in the Family:

Brawl webcomic that is mostly based around Kirby, great if you like nintendo and such, but can still be great even with basic nintendo knowledge.
Awkward Zombie:

AW has it's moments, it's another video game webcomic.
