I think I lost my sense of humor, I thought comics were supposed to make me laugh. But, I agree, it's too small and obviously made of Styrofoam is the boat didn't sink. I think I'm over analyzing the comic so I shall end my comment....now! :)
In support of the comic artist, notice the worrisome look on the little blond dude's face. After a few hours, his red capped buddy says "got one", and we see the elephant in that tiny boat. They're still fishing, its a bit humorous to think whats going to eventually happen to them in that darn row boat. The blond dude has reconsidered the "huge fun" of it all. Obviously the red capped dude is in support of legalizing weed.
