When flies fly behind flies, then flies fly behind flies.

ハエがハエの後ろを飛ぶとき、ハエはハエの後ろを飛ぶ。
BACK INTO ENGLISH
When a fly flies behind a fly, the fly flies behind the fly.
INTO JAPANESE
ハエがハエの後ろを飛ぶとき、ハエはハエの後ろを飛ぶ。
BACK INTO ENGLISH
When a fly flies behind a fly, the fly flies behind the fly.
That didn't even make that much sense in English.
