Bastards in Barston

Russians in bear shit

Spanish.

Closing me aye I hear: Bart 'tis in Barsin.

Of those listed, the closest is "Bart Simpson bouncing". But that might be confirmation bias as it IS the first one I read on the list. 2nd would be "Baptism piracy"

Is there a correct answer in there? I hear "That is embarrassing".

An even better answer would be which sentence corresponds to which region of the English world.

I'm used to that accent and I'm pretty sure you're right.

D'ylike dags?

I heard every single one - just depends on which written phrase I looked at first when the video started playing.
Try it, it's trippy. Focus on 1 option, then click replay.

That worked for me too, and worked when I said the phrase then replayed the audio for my wife. We both hear what we expect to hear.

Bat shit in purses

Lactating Pirate Ship - no question.

This seems the closest fit to me too, though I can hear all of them.
