天才與白痴 The Last Message (1975)

李護士（許冠傑飾）是神經病醫院的男護士，阿添（許冠文飾）則是雜役。一天，人個身背大包袱的大漢鄭明（喬宏飾）被送入院。他那隨身大包袱裏面盡是一些幾百年前的名貴陶瓷碎片。

鄭明竟然神經病發與世長辭。為了得知寶藏所在，他們找鄭明的女兒公主（艾綺蓮飾），得知鄭明經常到某處潛水。終被他倆在海底發現大批三百多年前的名貴瓷器。但最後阿添竟變成白痴，而李護士則被醫院解僱。

Li (Sam Hui) works at a sanitarium as a male nurse, and Ah Tim (Michael Hui) is a handy man. One day, a bearded old man is sent into the sanitarium with a large bag. Ah Tim manages to steal the bag, and finds antique fragments inside.

When the old man dies, the pair learn from his daughter that there is a sunken vessel that is loaded with much more than they already have, so they decide to go after the sunken treasure.
