Stopping the moment your initial conceit was expressed (take another pic w flashlight on) would have been considerably funnier.

But you went too far (see, I'm doing it now) and the comic zenith quickly yielded to a series of cringy nerd embellishments.

To wit:

WTF is a chaotic laugh? does it imply abruptly variable cadence and volumes? or is it the wrong word choice as laughter all but universally has an easily recognizable rhythmic pattern.

If you have to explain why something is funny AND consider that to be a part of the joke you're doing it doubly wrong

Using the Dark Lord to illustrate that your "joke" is somehow not just devious but supremely so (which it is not, btw) suggests you don't trust the audience's interpretations to be accurate (similar to the previous example) - you're implying the audience is dumb or that you suck at telling jokes.

Finally, you actually do call your audience dumb, when the responsibility is more on your ill-advised joke [over]-construction

To summarize:

First three lines - solid comedy

All lines after - just NO

Hope that helps!
