The G.I. Joe PSAs are 25 short parody clips made by Chicago filmmaker Eric Fensler under his Fensler Films banner1. Each video takes an original 30 second public service announcement from the mid 1980s G.I. Joe animated series and swaps in new nonsense dialogue over the animation, usually ending with a warped version of the show's famous 'now you know, and knowing is half the battle' tagline3.

Recurring bits include a manic kid yelling about a porkchop sandwich, a stranger offering body massages, and a baffled Joe team trying to explain a computer3. The comedy works because the original bumpers were played completely straight, with a Joe soldier delivering earnest safety lessons to wide eyed children. Fensler kept the animation and pacing intact and only replaced the audio, so the sincere cartoon frames feel warped rather than reshot.

The template is simple: take an earnest short form video, keep the original visuals and edit intact, and dub goofy non sequitur dialogue over the mouths1. New Fensler style parodies often close on a mangled version of the 'knowing is half the battle' outro to signal the reference3.
