Less Than Jake, "Richard Allen George… No, It's Just Cheez" from Hello Rockview (The Last Angry Man)
Skammentary: "Richard Allen George… No, It's Just Cheez" is a good song, but the pertinent part for our purposes is some communal bellowing on the track after the song proper's conclusion:
"¡Ay-yi-yi-yi, Cinco de Moustache!
The kids that are hip they grow on their lip,
They throw down their razors and don't give a shit!
Then grow and grow and grow and grow,
So let your mustache go! Oh yeah!"
