This week we return to juvenile humour [which may be NSFW].
There’s a curious scroll of images from Edo period Japan (1603-1868) of he-gassen, or a “farting competition”. The images show men and women happily expelling their gasses at cats, horses and even at each other. Apparently no one is safe!

According to the website Naruhodo “similar drawings were used to ridicule westerners towards the end of the Edo period, with images depicting the westerners blown away by Japanese farts”.
There is more over at Dangerous Minds, and you can find images of the whole scroll at the Waseda University Library.
