The final line of the job description

Fix light fixtures.
Become pseudo-competent in working the sound desk and photocopier, fixing problems as they occur. 
Monitor and maintain the churches social media presence.

Every job description has one fateful line which goes something along the lines of "and any other miscellaneous duties which arise."

Churches are no different.

And when you're typing up poems written by a homeless guy you just need to remember that every job has hidden tasks which fall into "miscellaneous... but important."
