https://www.bungie.net/en/Forums/Post/1550002?sort=0&page=2 On this day in 2009, Lil Stew13 posted the linked thread about finding a dog on his porch. Many users begun to parody the thread, posting their own variants, and the mods started handing out bans for spam. Since then, it's become a bit of a holiday here and has spawned its own Urban Dictionary entry. The holiday is recognised by posting parody threads. Happy Porch Day, everyone!
