The most awesomest comic out there is Dinosaur Comics by Ryan North. Here's my favorite one, so you get the gist of it (check out the mouseover text as well).
A while ago he hosted guest week 2009, where other artists made a Dinosaur Comics strip, each with his own style. The stand out IMO was by Andrew Hussie of MS Paint Adventures (weird stuff). It's one of the most clever comic I've seen. Enjoy you guys!
And the most awesomest script there is gives you a random panel 2 of Dinosaur Comics! Refresh! Refresh! Refresh! Refresh!
