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.

Advertising

 * There was an ad for fluorescent bulbs, bragging about lasting seven years. There's a kid who was newborn when the bulb was put in, and near the end of those seven years, he doesn't get a light bulb joke, saying "Change a light bulb? Why would anybody need to change a light bulb?"

Anime and Manga
"Rock: Okay, how many Polacks does it take to change a lightbulb? Revy: I'm guessing one to hold the lightbulb, and 99 to turn the house, isn't that it? Rock: Um... er... let's see. So, the Pope says to the guy who dressed like he's homeless... Revy: Yeah, "I thought I told you to get out of here yesterday". Yeah, good one. Do me a favor and just shut up and drive, will ya?!"
 * Axis Powers Hetalia plays with this in one strip in which Poland asks Lithuania to turn the table as he stands on it in order to change a lightbulb. Most likely a Shout-Out to the original joke.
 * They also do type 2 with Greece.
 * Black Lagoon does this when Rock tries to entertain Revy while they're running errand around town. Unfortunately, Revy knows all his jokes, which almost results in a car crash.

Film

 * A rather dark example of playing with this trope occurs in Disney's Mulan. Shan Yu dispatches two captured enemy scouts to deliver his warning to the emperor. After the two have already started to run away, Shan Yu casually asks an archer, "How many men does it take to deliver a message?" The answer the archer gives us is "one" and a drawn bowstring, implying that one of the scouts was murdered because he was unnecessary.

Web Original
"Q: How many tumblrinas does it take to change a lightbulb? A: You may think that a burnt out bulb needs to change just because the room is too dark for you to see anything, so it must be changed, but I don't care, it's beautiful, you should respect its right to be burnt out and learn to be more accepting of darker rooms, check your filament privileges you ableist scum.
