I just LOVE this Tumblr: So You're A Church Musician.
I don't agree with all the opinions expressed therein (for example, I'm all about new music!) but I do find all of it very funny! That opinion may be connected to the fact that it's not safe for work. :)
Also, honestly, if you are not a church musician, I can't vouch for whether you would find this remotely amusing. But if you have a church job, do check it out!
