在这部笨法39条片中,弟弟阿廣不覺得自己笨，皆因他有個攞正「心神耗弱者」證書唐氏綜合症的兄長阿清，自恃醒目開公司的大阿哥教曉他日本刑事法第39條，教唆阿清入屋行劫，拉到都不用坐牢。日文「3-9」的諧音與「thank-you」相似，於是連同女友，低一點的三人幫頓成為「多謝盜竊團」。阿廣的傻勁，讓人想起《奪命金》的三腳豹，而他們沿路偷竊，又似《父子》多過兄弟，然而這不僅有導演押田興將的親身經歷，飾演兄長的押田清剛，更是做返自己，窮不風流又如何，低調簡約的拍法，一路上看到的是不一樣的低角度笑料。
Two brothers: multiple problems. The older one has down syndrome. The younger one is developmentally challenged, and has brushes with the law and has debts because of his actions and his friends, but also needs to take care of his older sibling. When the boys' grandmother dies the brothers lose their home and are destitute and stay with a friend's friend and while the younger man is looking for a job things are bad enough that they still use the older brother to conduct some of their dirty work reckoning his illness shields him from the police, jail and the legal system.
