Ahhh. You've come to the right place.
Not really, but here's my list. Most of them have clichéd humour, but not bad.
Sluggy FreelancePenny Arcade <- not bad, but when it's funny, it's really funny
User FriendlyBlank It <- one of my favourites
Ctl Alt DelCtl Alt Del Sillies <- not updated frequently
Joe and Monkey <- this one's been discontinued, but it was good
Least I Could Do <- one of my other favourites, tons of 80s pop culture references
Everyday DecayThe Zombie Hunters <- this one is okay, but if you want a zombie comic, try Everyday Decay; The Zombie Hunters is rather slow (it takes literally months to progress the plot sometimes; it's been stuck in a flashback for so long, I'm wondering if the stuff before it was actually a flashforward instead)... and kind of mediocre (art's great, though)
Roomies/It's Walky/Joyce and WalkyShortpacked <- even more 80s pop culture references; same guy that does the Walky/Roomies ones
Lil Formers <- probably going on a limb here, but this one is rarely if ever funny. Don't know why I really read it anymore, but I do....
Rob and ElliotOut There <- more a "domestic" comic (for lack of a better term), but not bad
The Book of Biff <- one of my other favourites
There's another zombie web comic called Zombie Tales or Zombie Stories or something like that. It's by Boom Studios. I have the link at home. They also do another great one called Hero Squared. If you find Boom Studios, check these two out.
