They go to the planet of lost soles.

I think I find them but only after the other one is worn out.

There is a dark energy hiding deep inside dryers that scientist learned about years ago but refused to speak about. To dry out socks has been something that we have been wondering how to do for millennia. I believe it's a matter of cleaning the lint trap every 5th Tuesday of the month.

Due to centrifugal force, its thrown through a tear in space/time into the hosezone.

Many single socks, as well as pens from the bottom of your ppurse have a secret wormhole to another planet in another galaxy where they congrgate and live a single sock with pen existance.

Yes, and they are gradually filling up with lint. It may be how the big bang happened.

God demands it as tribute/sacrifice.

Sock goblins they use them as bedding for their young

I have an entire draw of identical socks so I'm over that rubbish.

I had one get stuck in the drain hose of my washing machine. That was one that didn't get away!

It left to rendezvous with the one shoe on the highway.

They’re dryer food.

It has been sacrificed to the sock monster that lives within the bowels of your dryer.
Be glad it hasn't started eating your underwear.

My enemies steal them to vex me. It's working.

Put them in a lingerie bag that zips

In MY house, it is either my drying machine eating them OR my dogs eating them. I haven't quite figured out which. LOL

Since reading this book in my teens I've fervently believed this is also where the single socks gou:

Douglas Adams "The Hitchhiker's Guide to the Galaxy"
“Somewhere in the cosmos, he said, along with all the planets inhabited by humanoids, reptiloids, fishoids, walking treeoids and superintelligent shades of the color blue, there was also a planet entirely given over to ballpoint life forms. And it was to this planet that unattended ballpoints would make their way, slipping away quietly through wormholes in space to a world where they knew they could enjoy a uniquely ballpointoid lifestyle, responding to highly ballpoint-oriented stimuli, and generally leading the ballpoint equivalent of the good life.

And as theories go this was all very fine and pleasant until Veet Voojagig suddenly claimed to have found this planet, and to have worked there for a while driving a limousine for a family of cheap green retractables, whereupon he was taken away, locked up, wrote a book and was finally sent into tax exile, which is the usual fate reserved for those who are determined to make fools of themselves in public.”

It is called divorce for a reason.

Since I do my own laundry and it doesn't mix with anyone else's, I never lose socks (for long). I may fidn a sock tht statioclly clung to the iside of clothing or a fitted sheet, but if I have an odd sock, I jus tput aside and the missign one alwasy turns up.

I have never figured it out, but will bet the second you throw the one way the other won urns p!

I don't know where thay go...I think your right on the blackhole.

It's in the big blower in the rear of the dryer that goes outside, or caught somewhere on the way/

We'll ask Tuco( The good, the bad, and the ugly). He never wore socks.

I found it! My octopus sock that was missing for a week was lurking behind the laundry basket.
