Petchtai Wongkamlao, born 1963, Yasothon Province, Thailand, is a Thai comedian, actor and film director. He is best known in Thailand by his stage name, Mum Jokmok and is a popular Thai television personality. He is variously credited as Mom Jok Mok or Mom Jokmok.
Mum started his career as a comedian in the Bangkok "cafe" scene (restaurants in Thailand with live music and comedy performances). He started his own comedy troupe with "Jaturong Mokjok". Mum became widely known to the public from the variety-game show Ching Roi Ching Lan hosted by Panya Nirankul. He appeared in comedy section with his group members and performed stunts. He also co-hosted with another popular game show Wethithong with Kiat Kitcharoen. He also has his own TV show named Mum Show, which airs every Saturday night.
Wongkamlao is perhaps best known for his film role as George, the comic-relief character in Ong-Bak: Muay Thai Warrior, a popular action film that stars Tony Jaa.
Mum reprised the comic-relief role in the followup to Ong-Bak, Tom-Yum-Goong, though instead of a con artist, as he portrayed in Ong-Bak, he was a Sydney police inspector. Much of the comedy in Tom-Yum-Goong had to do with Mum's character speaking English, which is not his first language. A gag reel over the closing credits shows him struggling with many of his lines.
His first starring film role was in 2001's Killer Tattoo, the debut film by director Yuthlert Sippapak. In the story of a group of bumbling hitmen, his character was named Dog Badbomb.
After Ong-Bak became a huge hit, Mum was able to write, direct and star in his own film, The Bodyguard, a wire fu action comedy film in which he portrays a bodyguard who is fired after the billionaire he is protecting is killed.He is often seen in smaller roles as well, including the hit 2005 Thai comedy, The Holy Man (Luang Phii Theng) as well as an uncredited role in Dumber Heroes, a part he has said he did for "a case of beer".
Mum is even an author, penning a short autobiography, The Untold Story.
