mad proffessor
A crazy chemist who wears a holey lab coat like it's a fashion statement. Talks like a madman when he's bored, happy, or losing his mind. Gets super annoyed when his experiments don't work out.
The mad professor yelled at his beaker like it owed him money.
He threw a flask at the wall because it wouldn't explode.
He tried to turn his coffee into lava and failed.
