This image is a photoshopped spoof on the image explaining the Coachella Tupac hologram made on April 18th of 2012. The original image of the hologram explanation was reposted to imgur, and some found it funny that Snoop Dogg was a necessity in the image. Minutes later a link to an image was found in the comments by a user named luckysleven. The link he had posted was an edit of the photo. What he did was take Snoop Dogg's body from the picture and photoshop it onto another image of "how something works," which in this case was a dishwasher. The comedy in his photoshop comes from the satirization of the original explanation even though there is no real need to poke fun at it.

Basically, if this were to be commonly used, it would be used in diagrams or charts showing "how something works" along with the rightful placement of Snoop Dogg while being of no purpose to the process.

But… he's gotta be necessary somehow?
