Non Sequitur Distraction

A character goes on a rant, presumably induced by some slight, and is caught up in a spot of Angrish. Or maybe they are giving a stirring speech, and are really on a roll, when they let out some Non Sequitur. When the rant or speech ends, the person being chewed out or preached to, with a perplexed tone, ignores 99% of the speech in order to single out the Non Sequitur.

Compare I Take Offense to That Last One, where the target (if being lambasted) only disagrees with one of the insults, implying that they admit the others are correct. Also compare You Make Me Sic, where in a situation you expect someone to have a strong reaction to a statement or insult they single out bad spelling and grammar.

 * This is a stock gag on Top Gear. with Jeremy Clarkson (and occasionally Richard Hammond) going off on a long-winded, over-the-top rant at one of the others (usually James May), at the end of which May will react to only one small part of the entire rant.
 * In one episode of Parks and Recreation, the gang is auditioning mural ideas. Jerry starts to give a touching speech about how his idea was influenced by his mother, but he accidentally calls the mural a "murinal." Seeing as how he's the Butt Monkey, nobody lets him live it down.
