I'm close; it's Lynn whining about how the New Media (in the form of a mildly silly and gross video game) are corrupting our children, destroying our morals and bruising fruit.
Panel 1: We see Michael rummaging through the bookshelf for an old-style video game cartridge; in doing so, we see that the Pattersons read books like The Cheese Wheel Murders and watch films like Gladiator from Mars.
Panel 2: He smiles and thought-bubbles "Cool! Mom HATES this one!" as he finds the copy of Booger Beasts that Elly had thought she'd hidden.
Panel 3: He asks John, who's just finishing up in the workshop, if he'd like to play a game; John says "Sure, Mike! Which one?"
Panel 4: Mike tells him "Booger Beasts! You take the Slimers an' I'll take the Crusts"; John is down for that because he hasn't been trained out of the habit of interacting with his children yet.
Panel 5: We see a panel full of sound-effects as John and Mike have fun together pretending to be the generals of mucus people armies.
Panel 6: This attracts the attention of misguided, ill-informed killjoy Elly; seeing her husband play a video game with her son has clearly horrified her. This explains why she looks freaked out as she yells "John! For heavens' sake"; he abbreviates "What commonplace thing am I not supposed to be doing now?" to a simple "What?!!"
Panel 7: As she stands there revolted by the 8-bit carnage, she admits that he's spending quality time with Mike but wishes he'd play something else.
Panel 8: The alternative she selects are checkers, Scrabble[tm] or some other sort of intellectually stimulating game with goals and stategy and good moral values; translated into English, this means that she is afraid of what the neighbors would say if they knew that her husband and children played video games.
Panel 9: Her bleating about how Booger Beasts is gross and disgusting and has no educational value whatever has pretty much the same meaning but has the subtext that she's been socialized to be revolted by the gross stuff that Mike is into. Whatever the reason for her disapproval, though, John tells her that they cannot stop now.
Panel 10: After all, he's winning. The fact that he's not horrified like he's supposed to be throws her for a loop.
Summary: One wishes that Elly would say what she means by times; what she clearly means is that she was conditioned to regard mucus as revolting and running around making noise as unfeminine and fears that the Neighborhood Association will exile them to Siberia for having video games on some other ill-informed, misguided but essentially well-meaning woman's blacklist in her house. Too bad that she needs to be the victim all the time; that keeps her from explaining where she's coming from. It's almost as bad as her being horrified that she has trouble breaking John to her will.
ETA: Lynn pledges her allegiance to not disturbing her readers with the knowledge that she's Canadian.
