Taylor lyrics in the most unexpected places

Have you ever encountered a surprise lyric when you least expected it? I just did and wanted to share...

My partner (36m) and I (35f) have been thinking about the idea of doing a Taylor/Travis themed Halloween costume - with him as Taylor and me as Travis :) However, he's not a fan of her music, with the exception of two songs (Cowboy Like Me and Tolerate It). Because of that, I rarely play TS when he is around. So imagine my surprise at this exchange when we were discussing the costume:

Me: Makeup could be pretty easy, if we got a good wig for you... just a red lip would probably do it
Him: Wouldn't I need to draw the cat eye sharp enough to kill a man?
Me:
Him:
Me: how did you even know that????

The surprise factor of hearing him just casually bust out that line caught me so off guard and made me laugh! Any other stories like this out there??
