An odour coming from a public toilet in Nakameguro smells almost identical to natto, according to eyewitness accounts.
“Bugger me Shintaro, that smells terrible, what did you eat?” asked Shintaro’s friend Hayaku Ikou.
“I don’t know, I haven’t eaten natto in over a month,” said Shintaro.
“Although you would be forgiven for thinking someone left a batch of freshly twirled natto in that cubicle.”
After further speculation, Shintaro believed he had been more than likely clogged up from eight consecutive days of mochi eating.
