Band Member: It's 4:20 somewhere.
4:20 is a code-term that refers to the consumption of cannabis and by extension, as a way to identify oneself with cannabis subculture or simply cannabis itself. In San Rafael, California, a group of teens calling themselves the Waldos, because, "their chosen hang-out spot was a wall outside the school", used the term in connection with a fall 1971 plan to search for an abandoned cannabis crop that they had learned about. The Waldos designated the Louis Pasteur statue on the grounds of San Rafael High School as their meeting place, and 4:20 p.m. as their meeting time. The Waldos referred to this plan with the phrase "4:20 Louis". Multiple failed attempts to find the crop eventually shortened their phrase to simply "4:20", which ultimately evolved into a codeword that the teens used to mean marijuana-smoking in general. Mike Edison says that Steve Hager of High Times was responsible for taking the story about the Waldos to "mind-boggling, cult like extremes" and "suppressing" all other stories about the origin of the term. April 20th (4/20) has become a huge day in which, people who smoke cannabis, gather in large groups to do so. Despite it being illegal, the police do not generally arrest anyone, even though they know where they are.
The title of this episode is the same as a song by Huey Lewis and the News from their 1983 album "Sports".
