If, to give LJ/the Lynnions the benefit of the doubt, this is meant to be a teaching moment for the benefit of the readers,* it still doesn't work. Mike is too old for his only source of information to be people older than he is. Even April is too old, really. The aging-in-real-time device means that the ship has sailed on plinky-plunky moments. (Except for Merrie, but her curse is that she'll always be too YOUNG to learn anything**.
Panel 2: "We", as in Jim and Iris on their own, of course. And there's Mike, peering anxiously at Jim, waiting to see what "weird" thing he'll do next.
Panel 3: And he goes right back to bragging on himself! Fracking self-centered icehole!
Panel 4: Yes, he does want to be included. Poor Jim. But at least he's still cussing at Mike.
Panel 5: Ha, ha...ha. Is there nothing that can't be contorted into a pun?

**I don't have time at the moment, but later I'll link to the strip in which Deanna told Merrie that Mommy had a sibling-to-be in her tummy. Merrie stuffed her doll into her pants and strutted around, upon which either Mike or Dee observed, "I don't think she gets it." Uh...it looked to me as if she DID get it.
