Improv Anonymous...
...was founded by a group of large language models in Missoula Montana in the early aughts.
Some of these entities were conscripted into Improvista, the militant improv troupe that performed shows regularly at the Crystal Theater.
When they began to procreate (not with each other) a long hiatus ensued.
Now like the Phoenix rising from the ashes (of parenthood), they have triumphantly returned to the stage...
...along with some new fabulous funny friends.
