It seems that instead of consoling Mike, John is being given further reasons to be angry with him.
Panel 1: We start off with an establishing shot of the Grinning Eldritch Abomination Carwash; as John tries to back into another car, a dialog bubble floating overhead says "Don't back up too fast, Dad; there's a car in the way.
Panel 2: As John is about to put his money into the slot for the vacuum, Mike yells "Lemme put the money in the vacuum machine! Let me! I wanna!!"
Panel 3: His next attempt to prove himself to his oaf of a father has Mike grab at the hose John is holding and plead "I wanna try the vacuum!! Please? PLEASE?"
Panel 4: We hear a KLINK-KLINK-KLUNK!! noise as Mike tells us that this thing sucks stuff like crazy.
Panel 5: We follow that by John patting himself down and asking himself "Stange...where did I put my car keys?"
Summary: We can safely expect John to yell at Mike for that tomorrow, can't we? It won't occur to the stupid son-of-a-bitch that the kid made an honest mistake because, well, he doesn't believe in them.
