By Hook or by Crook (Chinese: 鹹魚番生) is a 1980 Hong Kong kung fu comedy film produced and directed by Karl Maka and starring Sammo Hung and Dean Shek.

The film starts out with a thief stealing jewelry from the millionaire Chin Pai-wen (Tang Ching).

However, Chin's wife (Yau Poon-ling) suggests Skinny Gee (Dean Shek), a con man who catches crooks, instead.

He is a man named Fatso (Sammo Hung), who idolizes Flower Kid and pretends to be him.

Fatso and Gee later finds the real Flower Kid (Wu Ma), who is now old and retired.

The trio then proceeds to find Chung where they engage in a big fight at Chin's funeral.
