Big Nate by Lincoln Peirce for February 09, 1991
Mr. Rosa: What are you working on, Nate? Nate: Yet another masterpiece, Mr. Rosa! See? It's an ax fight between a bunch of ninjas and a squad of satanic marines! Awesome, eh? Mr. Rosa: Er...what's that in the background? Nate: A mushroom cloud! What else? Rosa: I hoped prehaps it was a tree... Nate: A tree? Make me yawn!
