You Don't Say

Loretta says she wouldn't say it. Then, after a brief pause, she says it anyway, after which she reiterates immediately that she wouldn't say it. Notwithstanding she's a fine one to comment on Leroy's weight, Loretta employs her peculiar brand of logic to insult Leroy in such a way as to confuse him into thinking about it for the rest of the day, thus providing the insult with great staying power.
