Bob and Doug McKenzie were created by Rick Moranis and Dave Thomas for the Canadian sketch show SCTV in 1980, where their beer loving hoser routine became a breakout hit. The characters later starred in the 1983 film Strange Brew and released comedy albums built around Canadian slang, winter and drinking beer. Clips tied to them circulate online as shorthand for goofy Canadian beer culture. This short shower effect fits that legacy, so editors reuse it whenever a scene needs an instant, recognisable beer soaked joke.
