Plot summary
The children are heading back to school, but Brighton refuses to go back because he feels "small" compared to other boys in middle school. Fran misconstrues this when Brighton tells her he was in the locker room at the time, to which Fran describes to Maxwell as being "gherkin". Maxwell exclaims "But he has such big feet!" (alluding to the myth of large features corresponding to a larger genital size.) Maxwell starts dating a woman, Leslie, who looks and sounds exactly like Fran.
