Panel 2: John's got a very womanly stance. And I can tell this is going to be all about Edgar being terrified of the sprinkler, then acting all brave when it's turned off.
Panel 3: Oh! Thought wrong; he wants to cool off! Still, he almost looks like he wants to mate with it.
Panel 4: Omigod, I really didn't want to see animal porn.
Panel 5-11: Whatever.
Panel 12: Now that's just a bizarre stance. And good lord, Edgar was humping the sprinkler for an hour?
