(Strip Number 5156, Original Publication Date, 20 July 1989)
Panel 1: When Mike comes up to Phil and says that Elizabeth's got ketchup and orange pop stains on her shirt, Phil says that's no good.
Panel 2: Since it's on Elly to clean it up and since he's a big kid himself really, he tells her she needs the ice cream and mustard stains he's made too.
Panel 3: After all, no one would believe they even went if they came home clean.
Panel 4: When Liz gushes about how ever neat Uncle Phil is, Mike agrees and then says it's hard to believe that he's related to Mom.
Summary: Sadly, there are signs that would make it easy for them to believe this. One such sign is his tendency to act as if it's an imposition to make his immediate environment kid-friendly while the other is to behave as if children are space monsters he can't relate to. You would think that Mike would have remembered what a tetchy jerk Phil was about trumpet lessons but, as we see here, the same asshole who got on his case about feeling as if he can't win becomes Captain Cool because he doesn't care about stains he doesn't have to deal with.
