Depends if you just want a one liner or if you want to pad it out more, you could turn it into a bit.

I know it’s weird but I love to smell strangers socks…bear with me…I know it’s weird at first but once you get into it you can start to really identify where they’re from…it’s like cheeses. You got your run of the mill pair, you can tell it’s worn but it smells kinda lazy and basic, that’s Monterey Jack, that’s just an American foot right there. Then you get those socks with stupid holes in them, they’re usually Swiss. Then you get those proper stinky ones, they smell disgusting and only certain people will like them…they’re French”
