There was a type of ointment called Clown ointment.
The description was as follows:
Applying this ointment will gradually turn the user into a clown over the course of one week.
Anyone who touches or is touched by the user will become infected and gradually turn into a
clown over the same period of time.
If the user comes into contact with someone they've already infected, then the process will
speed up.
Once infected, the same terms that apply to the user will apply to the infected too.
