Richard Matheson’s book “The Shrinking Man” was retitled “The Incredible Shrinking Man” by his publisher.
I suppose it’s possible for someone to think a shrinking man is not incredible unless told so bluntly.
Go ahead and try it yourself. Walk up to people at random and shout either “I’m the shrinking man!” or “I’m the incredible shrinking man!”
See which people are more impressed, stunned, or horrified.
If someone calls the police on you, forget about bail or calling anyone. Just wait until you’ve shrunk enough to fit between the bars.
Feel free to shout that out at the guards.
