ミイラ取とりがミイラになる

expression

the mummy hunter becomes a mummy; going for wool and coming home shorn; the biter bit

Proverbial expression meaning that someone who sets out to influence or capture another ends up being influenced or captured themselves. Often used when a persuader is persuaded, or when a seeker becomes like the sought.

• 友とも達だちを説せっ得とくしに行いったのに、逆ぎゃくに自じ分ぶんがその意い見けんに賛さん成せいしてしまった。まさにミイラ取とりがミイラになるだね。

  I went to persuade my friend, but ended up agreeing with their opinion myself. That's exactly a case of the mummy hunter becoming a mummy.
