This song was a geared from a love of science and skepticism.
I have heard of people claiming that they had been abducted by aliens, but it wasn’t until I read Michael Shermer’s book Why People Believe Weird Things that I was exposed to real life conditions that could lead to such visually and audibly believable hallucinations.
I thought it might be fun to indulge the hallucination by taking it a step further and trying to imagine what circumstances would actually be necessary for an alien race to actually feel compelled to probe a human anus for reasons besides basic scientific curiosity. I am not sure how far in the past the anal-probe meme began to emerge from the alien-abduction meme. I may have initially heard of the concept myself from South Park Season 1: Episode 1 Cartman Gets an Anal Probe and I am not sure how many cultural references exist before then.
That being said, I think that this kind of cultural phenomenon (the hallucination, not the anal probe) and the inner workings of the brain, are fascinating studies for anyone interested in science and skepticism.
