Where does the Transform Vampires/Werewolves into lawn furniture rote come from?

I remember the 90s when Mage players would tell Vampire players that a Mage can very easily transform a Vampire or Werewolf into lawn chairs, and that they could get quite a good collection. I didn’t know much about Mage those days, and I always supposed that was covered in some supplement.

These days, after reading some Mage books, I’m not so sure.

Was that infamous rote published in an official book? Which?

If not, anyone knows its origin? How did it spread so fast?

You can find the rote on page 610 of M20 as a kind of a joke. But I’m asking about the old days.
