How many Amish does it take to change a light bulb? None - we didn't have light bulbs in the 19th Century, so why would we need one now?
How many Jehovah's Witnesses does it take to change a light bulb? None - they prefer the darkness.
How many Arminians does it take to change a light bulb? Only one - but first, the light bulb must really want to be changed.
How many Buddhists does it take to change a light bulb? None - with the proper attitude, after a time of meditation, you will be perfectly content with a non-working light bulb.
(All of this, of course, is purely hypothetical. After Occasional-Cortex and the Demoncrats get their Green New Deal through, there will be no electricity to power a light bulb).
