NYC Graffiti I understand, example #2.
As anyone who's ever farted out their penis can tell you, a full-on Penis Fart does make you feel both sad + glad. First off, you're sad, because, well, releasing farts out of the penis is not something a healthy body does. But you're also glad because it just feels so good to get ride of gas any which way you can. So testify, mysterious Manhattan magic marker man. Testify.
