(Strip number, Original Publication Date, 26 January 1989)
Panel 1: We find Elizabeth trying to get John to confirm her belief that there's something wrong with her appearance. Since he doesn't get that she's got the same "I will not be consoled" complex as her mother, the dumbass tells her the truth that there's nothing wrong with her appearance in the futile belief that she's going to be cheered up.
Panel 2: When she asks if he thinks that her nose is too big, he says no.
Panel 3: Since John is stupid, he thinks that telling her that she has a cute, turned-up nose is going to fix things. He's wrong.
Panel 4: Since John isn't able to understand that what Liz was looking for was the answer to the question "Why am I ugly?", her running away in tears claiming "That's it! My nose is too turned up!" confuses him.
Summary: Since John's mind's eye is blind and he can never understand what people are thinking, this is just going to keep on happening. He's always going to be left flatfooted by obvious problems, be told what's wrong by Elly and propose stupid solutions because he's totally rocking the fecal encephalopathy.
