If I’ve been bitten by a clown can I go see a doctor or something or is it already too late for me
This exact situation happened in an episode of Dexter’s Laboratory called The Laughing.
Dexter gets accidentally gets bit and turns into a clown by nightfall. But don’t worry! Apparently the cure for clown transformation is to be defeated by the natural enemy of the clown, a mime.
I love this website and it’s advice on clown infection
