I once worked with a black woman named Helen H.
One day, the screen of her computer was full of the alphabet soup that often comes when they go on the fritz.
(I can't produce it here. Imagine it for yourself or remember the times that it happened to you.)
She said, "My computer's speaking in tongues."
That was a natural and unintended witty saying. To understand it, you ought to have some knowledge of Pentacostalism.
