Maybe what we need is a GONG, built to emit the specific Mortal Oscillating Resonance (MOR) that shatters reptilians outright, turning them into harmless gooey puddles.

Like what a Rife Machine does to parasites,..
only bigger,
reptilians bein' parasites on Humanity an' all.

Build it big as Madagascar.
Drop the International Space Station on it.
See what happens.
