This rare gem features the extraordinary stellar cast of two comedy giants on the same screen and the two Ma's (Ma Si-tsang and Sun Ma Si-tsang) performing together. Leung Sing-por as the wealth-feigning Au and Ma Si-tsang as penny pincher Ma already set the stage for laughter. Ma Si-tsang dons a hilarious moustache and adds panache to the character whenever he complacently twists his moustache, making his greediness almost lovable. The film features a zany plot 'twist' when the two Ma's, as father and son, try to attend a charity gala by having Sun Ma Si-tsang teach Ma Si-tsang to sing ‘Yu Hap-wan Expresses His Inner Feelings', one of the elder Ma's most popular repertoire. Ma Si-tsang gives a commanding seven-minute solo performance that captures the heart of the audience now and forever.
