* In a deleted scene for ''Film/HarryPotterAndTheGobletOfFire'', Snape goes around docking house points from students making out in the carriages, while Karkaroff follows him and tries to get him to show off his Dark Mark.

-->[[AC: [[RobotBuddy Pintsize]]]]: If the router starts a-rockin', don't come a-knockin'!
-->[[AC: Pintsize]]: ...Actually, if the router really does start a-rockin', do you think you could weight it down with something heavy? I don't want a cable to come loose and disconnect me.

* Subverted in ''WesternAnimation/TheSimpsons'':
--->'''Homer:''' Son, I've had some of the best moments of my life in the back of a car.
--->''(cuts to a picture of a rocking car)''

--->''(Interior shot of car reveals he's eating junk food)''

* There was a GettingCrapPastTheRadar version in ''WesternAnimation/TwoStupidDogs''. The two dogs went to a DriveInTheater, and ''every car around them was rocking''. Even the one on the screen!

* Referenced in ''WesternAnimation/{{Animaniacs}}'', where the Warners drop in on Dr. Scratchensniff and his date. Eventually, they start bouncing around, causing the car to jump as well. Outside, you see a mother forcibly turn her young son's gaze and push him away. [=*=]mwah![=*=] [[GettingCrapPastTheRadar G'night Everybody!]]

* [[GettingCrapPastTheRadar Suggested]] in the ''WesternAnimation/JusticeLeague'' episode "Eclipsed", where Flash uses the royalties for his energy-bar endorsement to buy a van. When Green Lantern asks why Flash, [[SuperSpeed of all people]], would need a van, he clicks a remote control that causes it to start rocking, and then shows off how the back is outfitted with a couch, stereo, and lava lamp like a mobile bachelor pad.

* ''Salome's Last Dance'' (1988). As Theatre/{{Salome}} starts her famous dance, the woman playing Herodias jumps into a crate with a beefy stagehand. Another stagehand sits on top, trying in vain to have a enjoy of wine while the crate is jumping up and down beneath him. Eventually the lid opens and a finger beckons him [[HammerSpace inside as well]]. As Salome's dance works to its peak, we briefly cut to the crate shaking wildly from the action inside.

* In the WesternAnimation/BeavisAndButthead episode "Beware The Butt", the title duo come across a rocking with the words "if this van's a-rockin' don't come a-knockin'" on it.

* Used in the film version of ''Film/HarryPotterAndTheGobletOfFire'' in a carriage. Snape comes a knockin'.

* In an episode ''Manga/YondemasuYoAzazelSan'', this can be seen as a gag when Azazel's searching for Beel.

* Parodied in ''{{Film/Scaramouche|1952}}'' when the actual activity involves [[SlapSlapKiss rather more being hit with frying pans]].

* Parodied in ''{{Film/Scaramouche}}'' when the actual activity involves [[SlapSlapKiss rather more being hit with frying pans]].

* In ''Webcomic/KevinAndKell'', Rudy Dewclaw has walked in on his mother and stepfather's more amorous pursuits on multiple occasions.

A form of SexyDiscretionShot where a vehicle or other small enclosed space is shown moving vigorously to show that its occupants are "[[UnusualEuphemism moving vigorously]]" too. (A common subversion is to then show that the vigorous activity in question [[InnocentInnuendo was not the one you were thinking of]].)

Sister trope to AutoErotica. May be used to help set the scene at MakeOutPoint. If they get particularly carried away, may cross over with DestructoNookie.

* ''Film/{{Titanic 1997}}'': In a car that's on a ship.

->''"Dudes! If the tent is a-rockin' don't come a-knockin'!"''\\

--'''Charlie''' to Sam and Dean, ''Series/{{Supernatural}}''

** Played UpToEleven in the episode where Homer visits Marge in prison: when Marge jumps on Homer, the trailer gets knocked over.

* There was a GettingCrapPastTheRadar version in ''WesternAnimation/TwoStupidDogs''. The two dogs went to a DriveInTheater, and ''every car around them was rocking''.
** Even the one on the screen!

** Also Tara's trailer at the end of 2x18, Hollywood Babylon.
** In 9x02, this also happens, but there isn't any sex going on, just killing. The guy was shown to be a vampire, but he wasn't the one doing the killing.

* Somehow, this was able to slip past the radar in ''WesternAnimation/TotalDramaIsland'', in this case Owen said 'boat.'

* ''MidsomerMurders'': In "Country Matters", TheVicar confesses to meeting her (married) lover in his van in a field. Although she claims they were just talking, the flashback shows the van start rocking almost as soon as they get in.
