Farting on a bible is a one-way ticket to being erased for disrespecting the gods.
A check should added to the clownbible such that farts are NOT disrespectful, due to farts being an inherent part of clown "culture", language and clownish behaviour.
It should, instead, turn any who fart into the clown bible into a true clown.
You get a "You intend to swear your life to the Path of the Jester? Very well, clown. Make me laugh." message, become clumsy and get a rainbow crayon.
Naturally, this would be gated behind there being a Clown chaplain.
