Twelve. One to change the bulb and eleven to do the paperwork.
None. Once the bulb goes out, they replace the house.
A. 3. 1 to find the bulb 1 to find a ladder and 1 to find a man.
Both should be changed regularly, and both for the same reason.
Three. One to screw it in and two more to hold down the editor.
Only one but it takes him seven weeks to get there.
