Однажды мальчик пришел с тяжелой корзиной, наполненной рыбой, фруктами и дичью. Он постучал в дверь, и Свифт случайно открыл, "Вот," сказал мальчик хрипло, "мой мастер прислал вам корзину с вещами".
Свифт, недовольный манерами мальчика, сказал ему: "иди сюда, приятель, и я научу тебя как немножко вежливее доставлять посылки. Подойди, представь себя Свифтом, а я буду мальчиком." Затем он вежливо снимает свою шляпу и обращается к мальчику: "Сэр, мой мастер прислал вам небольшой подарок, и умоляет вас сделать ему честь, приняв его."
"Ах, очень хорошо, мой мальчик" , ответил мальчик, "передай своему мастеру, что я очень обязан ему, и вот полкороны для тебя"
Свифт засмеялся от души и дал мальчику корону за его остроумие.
