i’m partial to the classics. i still remember one from my childhood and it makes me laugh a lot two decades later:
Here I sit, broken-hearted
Came to shit but only farted
that was written by Walt Shitman
A local used bookstore had such eloquent grafitti and drawings that looked like the works of monks and scribes. That place was also a hundred safety violations in a trenchcoat, so it got the cabash. I miss it dearly. 😢
I saw one at this skeevy little truck stop in rural western PA that had written neatly in tiny sharpie at perfect eye level above the urinal:
get blown
[local phone number]
something about the directness and brevity still makes me laugh.
