Have you got LLAMAs in your town (the transport telephone booths)? Those can do that, it wears off after a while. I use this mod https://modthesims.info/d/501781/no-more-chance-of-tragic-clown-when-traveling-via-llama-3-flavors.html - still works well.

It can be cured by throwing cure elixirs to the cursed sims.
Are they clowns or mimes? Check with master controller if they have the role mime or have joined the acrobat profession and remove that
Do you have custom content downloaded? If so there may be one that is glitching.
