Explain xkcd: It's 'cause you're dumb.
Cueball's neighbor and her boyfriend like to engage in loud sex, which keeps him awake at night. He then gets revenge by getting a loud girlfriend and installing an elliptical reflector dish in such a position that it focuses the noises made during sexual activities on his neighbor's bed. The noise is apparently loud enough to exceed the threshold of pain for humans.
The title text mentions that a spherical or parabolic reflector would not work here.
- [Man in bed, covering his head with pillow.]
- Narrator: My neighbor has loud sex.
- Narrator: Good for her and all, but it keeps me up at night.
- [Man and neighbor coming out of their apartments.]
- Neighbor: Sorry, could you hear us last night? Oh, you know how it gets sometimes.
- Narrator: (small) Not really...
- [Girl with "LOUD" and an arrow pointing to her.]
- Narrator: But tonight I finally get my revenge. Because now I have a loud girlfriend too.
- [Diagram of an elliptical reflector dish.]
- Narrator: And an elliptical reflector dish.
- [Man and his girlfriend having sex, with dish behind them, with sex sound effects coming off the dish, through walls, to his neighbor sitting up in bed while holding her head in pain.]

It is still strange: On sexual comics we got many technical discussions and here (a sexual background is also given) we can imagine some "aberrant sexual behavior"? How that single neighbor girl should come to this? Or will that dish brake and fall onto this two people in the bed on the left? I would just say this is only a technical comic, with some sidesteps. --Dgbrt (talk) 23:10, 4 June 2013 (UTC)

- Is sex more important than science? Maybe, but while everybody knows how to perform sex, they do not understand how to do this science.--Dgbrt (talk) 17:08, 24 December 2013 (UTC)
I had interpreted the "aberrant behavior" of the other mehtioned types of reflectors as referring to the way they would focus the sound- a parabolic dish would focus sound into a parallel beam, annoying the entire hallway (but not any one person as much- compare sunlight coming through a window to the same light, routed through a magnifying glass, where the glass is the ellipsoidal dish); while a spherical dish would focus the sound right back on Cueball himself.
Also, I dobut the threshold of pain could actually be reached here, since it would be hard for the intensity of the sound focused in the neighbor's room to exceed that of the sound in Cueball's own room- and I'd be surprised if Cueball's friend produced enough sound to make her own head hurt. My guess is that the neighbor had just been startled awake.

- "Aberration" should be understood here as a sound equivalent of wikipedia:Optical aberration. An spheric or parabolloidal reflector wouldn't focus in one point sound from a point source. Of course, there is also a double meaning with aberrant sexual behavior.--Pere prlpz (talk) 12:49, 15 December 2015 (UTC)
