Sum Na Rankhan

Sum Na Rankhan (Thai: ส้มน่ารำคาญ RTGS: S̄̂m ǹā rảkhāỵ) is a Thai comedy web series created by a Thai film director and screenwriter of Chinese descent Wisit Sasanatieng in 1995. It stars its creator as an anthropomorphic orange who annoys other fruits, vegetables, and various other objects by using jokes, which are sometimes crude.

Despite the show's negative critical reception, the show's popularity after its first episode led to it becoming the subject of a TV series, a video game, a range of toys, backpacks, couches, pillows, blankets, lunchboxes, drink bottles, mattresses, towels and a T-shirt line. Other accessories, such as costumes of the series' characters, have also appeared on the market for the company.

Since its inception, the Sum Na Rankhan YouTube channel has amassed over 5 million subscribers.
