Parker has had it with Pull ups. He would wear a diaper any day. He's just so sick of how thin they are and how they occasionally fall off. But he doesn't want to slip it off, that would give it too much respect. Have you seen commercials for that particular brand of pull ups? The ones with velcro on the sides "just in case"? Parker is wearing that brand. He pulled that velcro support right off, acting like he had an accident and just let the disgraced pull up fall to the floor. He then threw it into a burning barrel as a further insult. If a pull up has that velcro thingy, it isn't a pull up, it's a very thin pull on diaper.
