clones

After scientists perfected the cloning technique, they decided that each person should have a copy, which would be stored until the original person died, at which point the copy would carry on. At first it was decided that the clones would be made in alphabetical order. However, many people without relatives argued that they should have priority so that they could carry on their names. The scientists decided this was fair and decreed, "Let him who is without kin stash the first clone."

That thought occurred to me after your first post.

And I don't get the joke...

I get the joke, I think

Reminds me of the book "spares" by Michael Marshall Smith, where clones are being farmed and used as spare parts for those that can afford them.

Or one of a thousand other films/books on the same subject, of course.

The punchline is a play on that saying "let him who is without sin cast the first stone" isn't it?

If I'm wrong I'll feel silly

yep

YAY I got a joke
