(Strip Number 1317, Original Publication Date, 19 July 1988)
Panel 1: We figure out why the boys are melting when Mike declares that the Enemy is sneaking up on his blindside; this means that The Noble Scribe To Be doesn't understand what cross-ventilation is.
Panel 2: The nitwit's response is to make too big a deal of loading up a pea shooter to fire out of an improvised gun port.
Panel 3: Brian plays along by declaring that the cardboard tube they call a torpedo tube is ready.
Panel 4: We see Lizzie telling Dawn to turn on the hose that she's shoved down the cardboard tube on NOW!! thereby "settling" the issue by just plain destroying the box.
Summary: The simmering aggression that made dimwit Mike sit in a hot damned box like a turd drying out on a bad stretch of road because he needs to 'win' is going to boil over now that said box is wrecked. This leads into Elly once again "solving" the problem by dumping him on someone else because the presumptuous jerk expects them to fix what she won't.
