If you’ve seen the trailer for the 2011 documentary Shut Up, Little Man! you may have noticed something familiar. If you haven’t, watch the trailer below and pay super close attention at 8 seconds in. Or just look above.

It’s a Joynt t-shirt! From the late 1980s.

Shut Up, Little Man! is a documentary based on the audio vérité recordings of two argumentative and violent alcoholics, Peter J. Haskett and Raymond Huffman in San Francisco. Bananafish magazine arranged for a commercial release of the tapes in 1992. You may have heard about the recordings on This American Life, Season 1, Episode 7.

Who’s wearing the Joynt coaster shirt? The recordings were made by "Eddie Lee Sausage" and "Mitchell D." – shown in the video still above – who lived in an apartment building in San Francisco's Lower Haight district. Eddie Lee and Mitchell moved into the apartment in 1987, and discovered that their neighbors, Haskett and Huffman, argued nearly constantly, with Peter often shouting "shut up, little man!" at Ray. Eddie and Mitchell began tape recording the arguments, and distributing copies among their friends.

Not sure which dude is actually wearing the shirt. Or how they got one. Hey, it was the eighties. Crazy times, man. Crazy. Times.
