A trivia question for y'all

I just sent a question into one of my favorite radio game shows, "Says You", which is a game of two panels having to answer questions about words.

And I'm going to post it here, too, because I'm pretty darned sure that none of the panelists read my livejournal or facebook, so I'm not spoiling anything.

One of their standard question types is to be presented a list of things, which all have something in common, except one of them. The panel has to tell which one the odd one out is, and why.

I sent in the following list:
Lillian Virginia Mountweazel
Dord
Esquivalence
Algoe, NY
Ralph Marterie's "The Song Of Love", which peaked at #84 on the Billboard charts on December 26, 1955

Four of those have something in common, which the fifth lacks.

I'll put the answer in comments, so that you can all guess if you like.

A thing which exists, and isn't actually anywhere near as bad as it sounds.

The Pickleback. A thing which sounds like, and might be, a dare. A shot of whiskey chased by a shot of pickle brine.

It exists, and apparently, there are people who like it. And I am a curious person and willing to do horrible things to myself out of curiosity.

I have a bottle of good-but-not-so-good-that-this-would-be-sacrilegious whiskey, the Costco house-brand bourbon -- distilled and aged by Jim Beam, and better than their basic well Jim, but not as good as their real high-end stuff. A good everyday dram, good enough to serve to guests that you like, but not quite good enough that you'd give it as a birthday present.

And I had a jar of organic, naturally fermented pickles, with a live-culture pickle brine, not quite as salty or vinegary as most pickle brines, but with a tasty blend of whole spices, and a lot of deep complexity because of the fermentation.

I mean, it's not like I'd normally drink pickle brine, even this stuff. But given that I was curious, this seemed like a reasonable thing to try.

And -- it's not horrible. It's the sort of thing that I probably could become a real fan of, upon repeated exposure. It's not so amazing that I'm going to become an evangelist for the idea, but it's not actually disgusting. In terms of novel taste experiences I've had recently, I'd put it pretty close to the breadfruit pancakes I made, maybe slightly better. Again, that's with the organic fermented pickle brine -- I think that, with a more usual pickle brine, it would be slightly worse. But still not horrible.
