Reminds me of a joke from long ago: Two old spinster sisters saw an add in the catalogue for a stinkless outhouse. They thought that would be a nice change; and the laborer who dug the outhouse and installed it assured them it would be stinkless. But within a month, their new outhouse began to smell awful; so they called the outhouse company, who sent out a man to investigate. He shone his flashlight down the hole, and exclaimed: “Well, no wonder it stinks! Somebody shit in it!”
