In news that makes me want to go down the river and not across the bridge for writing, Kim Kardashian and sis Kourtney revealed to the world on Sunday night's 'Kourtney and Kim Take Miami' just what their vaginas smell like, effectively eliminating perhaps the sole bit of private information either of them had.

They couldn't just give out their Social Security numbers?

Khloe started it, telling Kim and Kourtney that "pineapple juice makes everything sweeter." And by "everything," she meant "vaginas."

This led her two shameless sisters to have what Kim called a "vagina smell-off," in which Kourtney and Kim Took Pineapple Juice. They guzzled it for an entire day in London, then wiped themselves on towels for Khloe to sniff.

"Do I want to be the judge of the pineapple p----? Not really," Khloe admitted. "But we're sisters -- if I can't smell their p---ies what else am I supposed to do?"

I dunno, get a job? Learn to knit? Not smell them?

For what it's worth, apparently Kourtney's vagina emitted an aroma of a "tropical island." While Khloe was reluctant to "smell Kanye's d---," she admitted that Kim's nether regions smelled "like a flower p----."

Tune into the video above to find out who the winner is. Just know that if you hit "play," it's definitely not you.
