Panel 1: Now that school is out for the summer, we find a mutant girl asking Mike if he passed. When he says "Sure", she/he/it declares that ever neat and hopes that they might be in the same class next year.
Panel 2: When she says "Bye! Have a good summer", Mike says "See you 'round" and Gordon says "It's over, man. No more school."
Panel 3: Mike, Lawrence, Gordon and Brian whoop with delight because they're free for the next ten weeks.
Panel 4: A pall of confusion descends upon them when Mike asks "Now what?"
Summary: This is why last Saturday's strip is a sinister joke to me. As next Sunday's strip proves, if not provoked or ordered to do something, Mike's default setting when given time to do things is "stand around like a wooden Jesus in a country graveyard." We're about to see being provoked turn into being ordered to do something momentarily.
