The Ghosts Must Be Crazy (Chinese: 鬼也笑; pinyin: Guǐ yě xiào) is a 2011 Singaporean comedy horror film directed by Mark Lee and Boris Boo.

Sometime in the 1990s, late at night, two soldiers (played by Suhaimi Yusof and Khariudin Samsuddin) dig a shellscrape during a military exercise, encountering human hair buried in the ground.

Another soldier, Ah Tan (Dennis Chew), comes to see Lieutenant Chua to get a day-off or light duty too, citing ill health (he suffered for internal injuries), but gets rejected as well.

Eventually, the female ghost reveals herself through Ah Tan's body, frightening Chua enough, who then runs off into the woods where his screams echo throughout (his final fate is unknown).

Later, he visits a gambling parlour and after winning $35,000 as Ah Hai expresses congratulations, chooses to continue his betting, which ultimately turns sour and causing him to lose a large portion of his money.

Spooked, he runs to the carpark exit ramp and believes himself safe, only to watch thousands more come from all directions on the ground and surrounding him, all rising into the air as three float near his face and explode.

Ah Hui's initial shock from being told by her family for them to get married becomes disgust as he felt Xiao Juan was ugly and more man than woman (due to her coarse voice).

Later, Ah Hui goes to a Chinese prayer-supplies store and at the insistence of Xiao Juan purchases a large quantity of luxury goods and items for the Afterlife (including a large 3-storey mansion, 3 iOne tablets (mock-up of iPad) which comes with a free jet plane and ten cars (all of the cars were mock-up of Mercedes-Benz E500), among others) and is later married at a temple ceremony to Xiao Juan before spending the first night together consummating their relationship.

The next day, Ah Hui walks around in a daze and gets knocked down by a hearse while crossing the road but is unaware he had been killed until he saw his bloodied corpse lying on the ground, surrounded by a large group of concerned passers-by.

This second part then ends with a phrase (in Mandarin) which states, “If you choose to make a deal with the devil, you must be prepared to pay the ultimate price”, before the credits roll.
