How many astronomers does it take to change a light bulb?

“Change a light bulb? What for? Dark is good.”
“Oh, if you insist. Ah…”
“One, to measure the bulb’s black body radiation at room temperature to verify it is totally dead. Then…”
“One to argue about the measurement’s calibration.”
“One to analyze the pre-failure luminosity and classify the bulb for replacement.”
“One, specialist, to fill out the required requisition forms and attach funding requests as needed.”
“Another specialist to determine if the Coriolis force is sufficient to screw the replacement bulb into the socket…Just kidding about that one.”
“One to bring in the elevation device…uh, ladder.”
“One to ascend the device, ladder, and do the deed.”
“That’s how many? I’m sure I’ve missed a bunch, astronomers like big numbers.”
