The Bus Uncle

The Bus Uncle is a Hong Kong Cantonese viral video depicting a verbal altercation between two men aboard a KMB bus in Hong Kong on 27 April 2006. The older and more belligerent of the two men was quickly nicknamed the "Bus Uncle", from the common Hong Kong practice of referring to older men as "Uncle" (阿叔). The altercation was recorded by a nearby passenger and uploaded to the Hong Kong Golden Forum, YouTube, and Google Video. The video became YouTube's most viewed video in May 2006, attracting viewers with the Bus Uncle's rhetorical outbursts and copious use of profanity, receiving 1.7 million hits in the first 3 weeks of that month.

The video became a cultural sensation in Hong Kong, sparking debate and discussion on lifestyle, etiquette, civic awareness and media ethics within the city, and attracted the attention from media outlets around the world.
