The only think Derek — I’m sorry, “Dman” — had to say about this note was, “i live with some girls, and one is pretty funny.” Something tells that “funny ha ha” isn’t what comes to his roommates’ minds when mopping up Derek’s puddles of urine.

Our submitter spotted this sign next to the door of a video game shop in Australia. “I’m left wondering how often this must have occurred to warrant the sign,” she says.

Apparently, when is comes to judging the average person’s ability to correctly assess, “Should I urinate here?” you really can’t be too careful.
