Paya (Zelda) - About that birthmark

I love how Impa is so blunt and crass about this. She's normally all "plot important serious shit yadda yadda", and when you first ask about Paya's mark, she calmly tells you to change the subject. Then when you finish the Stolen Heirloom sidequest, she suddenly decides to say it outright. I say that Impa's sudden mood change is just as funny as the fact that the mark is on Paya's ass.

Is this the first Zelda game to use the word "butt"?
