From the USA:

The Problem: 
Changing a lightbulb the Christian way!
How many Christian does it take to do it?

Charismatic
Only one: Hands are already in the air!

Pentecostal
Ten: One to change the bulb, and nine to pray against the spirit of darkness.

Presbyterian
None: Lights will go on and off at predestined times

Roman Catholic
None: Candles only

Baptist
At least fifteen: One to change the bulb and three committees to approve the change and decide who brings the potato salad.

Episcopalian (Anglican)
Three: One to call the electrician, one to mix the drinks and one to talk about how much better the old one was.

Mormons
Five: One to change the bulb, and four wives to tell him how to do it.

Nazarene
Six: One woman to replace the bulb while five men review church lighting policy.

Unitarians
We choose not to make a statement either in favour of or against the need for a lightbulb. However, if in your own journey you have found that lightbulbs work for you, that is fine. You are invited to write a poem or compose a modern dance about your lightbulb for the next Sunday service, in which we will explore a number of lightbulb traditions including incandescent, fluorenscent, three way, long-life and tinted, all of which are equally valid paths to luminescence.

Methodists
Undetermined: Whether your light is bright, dull or completely out, you are loved. You can be a light bulb, tunipbulb or tulip bulb. Church-wide lighting service is planned for Sunday. Bring bulb of your choice and a covered dish.

Lutherans
All of them: Lutherans never change light bulb or denomination, even in burnouts.Faith alone carries them through the period of darkness until they, including bulb, are turned on again by love and all, not only bulb, shall be changed.

Kingdom of God
Christ Himself: Ever since God said „Let there be light“, there was light, with or without bulbs. In case of darkness change of anything doesn’t help unless Christ Himself comes to supply darkness with hands to grasp the light.
