Light Bulb Joke

""How many members of a specified ethnic demographic does it take to change a light bulb?" "Ten-- one to screw in the light bulb and nine to act in a manner stereotypical of their ethnicity.""

A stock joke about poking fun at groups with the ridiculous ways they would change a light bulb.

The common format is "How many (group of people) does it take to change a light bulb? X+1. 1 to change the bulb, and X to (humorous caricature of group)."

Another is a means to accuse them of Pride: "How many (people) does it take to change a lightbulb? One. He holds it up, and the universe revolves about him to screw it in."

This can sometimes be mocking other groups, but it can also be Self-Deprecation of one's own group.

Take ourselves as tropers: "Q How many tropers does it take to change a light bulb? A One, but someone will put the old bulb back with a Justifying Edit."

Another example: "Q How many tropers does it take to change a light bulb? A One screws in the lightbulb, while nine others mark the ways he was similar to other lightbulb screwers."

It also has many variations (including noting the pun of "screw").

The original joke is in some danger of being a Forgotten Trope:

"Q How many (insert Funny Foreigner of choice here) does it take to screw in a lightbulb? A Two, one to hold the bulb, and one to turn the ladder."

Of course this joke shows up in fiction as well, and examples here should be limited to such. It's generally acknowledged as being a Stock Shtick, and thus usually a sign that the character doesn't know any better jokes. It's also a good candidate for an Orphaned Feed Line.

In Speculative Fiction, the exact format of the joke may be altered slightly to allow for the lack of light bulbs.

Compare Knock-Knock Joke.
