Don't turn it on.
Title text: Don't turn it on.


This comic takes place in a scene from the third theatrically-released Star Wars movie, Return of the Jedi, wherein Darth Vader confronts his son, Luke Skywalker, who had recently surrendered to Imperial soldiers. In the movie Vader notes that Luke Skywalker has constructed a new lightsaber following the loss of his original during their duel on Cloud City (Luke Skywalker's original lightsaber actually having been Anakin Skywalker's second). In this comic, however, Darth Vader has accidentally discovered his son's Fleshlight (a male sex toy designed to imitate one of various orifices, most commonly a vagina), which he apparently brought with him on the attack on the Forest Moon of Endor. From a certain angle, a Fleshlight could be mistaken for the handle of a lightsaber, without the blade extended. Like many children, Luke Skywalker is attempting to hide evidence of his sexual activity from a parent.

The title text refers to the fact that if Darth Vader turned the Fleshlight on, instead of creating a blade of pure plasma (or energy) suspended in a force containment field the device would simply vibrate, revealing it for what it really is.


[Darth Vader is holding what appears to be a powered-down lightsaber and talking to Luke Skywalker.]
Darth Vader: I see you have constructed a new lightsaber.
Luke Skywalker: ...Yes. That is definitely what I did.
Closing: Vader finds Luke's Fleshlight.
