Naughty Boys (Chinese: 扭計雜牌軍; Jyutping: nau2 gai3 zaap6 paai4 gwan1, released in the Philippines as Supercop Protectors) is a 1986 Hong Kong martial arts crime comedy film directed by Wellson Chin, produced by Jackie Chan, and starring Kara Hui, Carina Lau, and Mars.
In the film, an ex-convict discovers that his gang's hidden loot has been replaced with useless rocks.
One of them, Sheng, is released from prison early, and discovers that someone replaced the diamonds with rocks.
The three other convicts mistakenly think he is keeping the diamonds for himself, and a chase for Sheng ensues all throughout Hong Kong.
