This story was inspired by two interesting house guests I had earlier this month. One of them apparently had her lip blown up by a cockroach and in my head this was how the picture formed. The image of a cockroach trying to blow up a shark is hilarious especially since they're both creatures that existed since before the dinosaurs.
I actually don't know which has been around the longest - the shark or the cockroach. Apparently there's even an unanswered question on wikianswers!
I like how my cockroach turned out - especially the "yee-ess" response in the 2nd panel.
