Got a Pen? Sketch This Comic!

Man to dog: ...blah blah blah blah cause i've got a thumb, you see! superior evolution, damnit! that's why we rule the world!
Dog to himself: wish he'd shut up and actually use that can opener...
Dolphin A: If you had a thumb, what would you do with it? Hitch hike?
Dolphin B: I'd stick it up your butt!
Both: HAHAHAHAHA!
Dolphin A: Awesome.
