It's not a bulb it's a globe.
Six-1 to change the bulb and 5 to sing about how much they miss the old one.
Four - three to cut a hole in the roof and one to change the bulb.
Two, one to hold the bulb and one to rotate the universe.
It takes four. One to screw in the bulb, and three others to watch and say, "Really dude, you look huge!"
Third as many as for a regular bulb.
Just two. One to politely ask and the other to politely help.
