The wedding Dear Dumb Diary readers have been anxiously anticipating is about to become a reality:

Jamie's aunt and Angeline's uncle joined together until death do they part -- or until the divorce Jamie has been feverishly wishing for since they started dating finally happens. Now, three of Jamie's most dreaded nightmares are about to be combined into one unbearable event: ? Very VERY poofy brown dresses ? Wedding clogs ? A lifetime of being related to Angeline, a.k.a. Blondewad Jamie has just one word for this kind of horror.

小心啊~~~笨蛋症可是會傳染的！不然你看，為什麼大家都在做笨事？卡蘿阿姨和戴副校長終於要結婚了！為了婚禮，每個人都有好多事要忙，而我們的任務就是──穿上超醜的伴娘服和摔跤木屐！天啊，為什麼大人們會有這種笨到不行的點子呢？

但是說到「笨」，臭臭絕對是笨中之笨，不知道牠是肚子太餓，還是想把自己變得漂亮一點，居然吞掉了一整罐亮粉！還有莎莎突然異想天開，替我臉上的痘痘取了一個超可笑的名字！大家到底是怎麼了呢？下一個登上「笨蛋」寶座的，會不會就是可愛的柯潔美？
