Panel 1: We find a rather anxious-looking John trying to build a model plane when one of the pieces snap.
Panel 2: He screams in rage.
Panel 3: Michael comes over and asks John what he's doing.
Panel 4: John curses under his breath and explains that he's building a model plane.
Panel 5: When Mike points out that the glue John just glopped on the windshield isn't going to come off, John gets really pissed.
Panel 6: He then bellows that he knows that.
Panel 7: Since Mike hasn't realized yet that it'd be a great idea to get away from John when he's upset despite having lived with the belligerent fool all his life, he tempts fate by trying to interrupt John when he's cussing out the prop for going on the wrong way.
Panel 8: John bellows at Mike to make him go away.
Panel 9: Mike asks Elly why Daddy is building that dumb thing for if it only makes him angrier than he usually is.
Panel 10: She says that it helps John relax.
Summary: John really, REALLY needs to learn to control his temper. It isn't, after all, Mike's fault that he's a clumsy clod who rushes through things like an idiot.
