4 March 1983
Matthew Krok (born 4 March 1983 in Sydney) is a former Australian child actor best known for playing the role of schoolboy Arthur McArthur on the Australian sitcom Hey Dad...! from 1991 to 1994. He also appeared in a popular Sorbent toilet paper advertising campaign at around the same time.
During the peak of his stardom in the early 1990s, Krok appeared as a celebrity guest on Wheel of Fortune and was also frequently referred to as "the little fat kid from Hey Dad...!". In an infamous The Late Show skit, "Arnold Schwarzenegger" (played by Tony Martin in heavy prosthetic makeup) jokingly revealed that the plot of the then yet-to-be-released Terminator 3 revolved around killing him and said, "Hasta la vista, little fat kid!".
Prior to this, he commenced studying for a degree in civil engineering at the University of Western Sydney and has since transferred to the University of New South Wales where he is undertaking a double degree in civil and environmental engineering.
