Met a chick who pulled the same one my ex did (literally word for word, lol)

"I'm not wearing heels today, does that make you feel taller?"

I don't remember how I responded to my ex when she dropped it on me, but I do know for the more recent instance I was having too much fun at the time to actually respond (I was grinning because I was alternating between groups of friends at the event, and I think the shit test just added to my amusement so I answered her with silence + a goofy ass grin).

Anyway, I was meditating earlier and it popped up in my head again + I recalled the shit test 101 guide in the sidebar (agree and amplify/change topic/ignore).

Since you guys are much more experienced I was wondering what other ways to shut down this sort of shit test would be? I can't possibly have pulled off the most effective counterplay, any ideas for better responses?
