the last arrow in my quiver of whimsy

i was playing around with google assistant tonight on my new phone. (not that i've never had google assistant before, but...)
i asked her to recite me a sonnet and she apparently thought she was complying but gave me a poem by yosa buson:

over-ripe sushi,
the master
is full of regret.



so then i asked her for a haiku and she gave me this:

don't call me, he says.
he's off on new adventures
roaming in the woods.



and i tried googling it and it doesn't appear anywhere on the interwebs so i'm curious who sourced it.
