Someone's imagination? That would be my guess, since the only reference to it is tumblr, Pinterest and Facebook images.
If it's Bukowski it sounds like it would have been part of a letter, but I don't find it, or anything like it, in any of the letter books (not including On Writing, which I don't have a pdf for yet).
It has the same English-as-a-second-language quality that the find what you love "quote" has, which leads me to believe it's not a Bukowski quote (or it's a bastardization of an actual Bukowski quote). I'm not like an ordinary world?
We're going to need a separate forum for these soon...
I sometimes wonder if these quotes maybe someone say in germany, reading a buk book in german, and trying to translate the quote back to english. That's a huge benefit of the doubt scenario... because most of the shit is probably just made up.
