In the film Kick Ass Girls 3, Chrissie Chau Sau Na and her two junior colleagues DaDa Lo Chung Chi and Hidy Yu Hiu Tun were paid handsomely to work in a private security firm in Malaysia.
In a scene, they received the royal treatment at a gigolo shop, and co-stars Matt Chow Hoi Kwong and Alton Yu Dik Wai, who played characters who worked at the shop, used every trick to seduce the trio.
The funniest scene was when Alton Yu had to provide his service to Chrissie Chau.
According to an article in hktopten, he massaged her toes, which made her scream with pleasure.
This scene was the hardest to hold their laughter in because the guys often improvised.
Even the sound recording technican's hands was shaking from all the laughing.
