The 'Gag Factor' scenario. Microphone on floor near UPSIDEDOWN peniley retch-beaten woman head. Cable runs from microphone to a small speaker inside a parakeet cage on the nightstand next to gag sofa. Every reactionary piston-fueled noise emitted by the woman causes the parakeet to flutter about in its cage in great alarm and agitation. Both parakeet and INVERTED head are onscreen at once, whether through split screen or framing mise en scene. Thanks.

P.S. When I was a kid, I had a cobalt blue budgerigar named "Pepper".

Oddly enough I watched a Japanese porn (go figure) that had a somewhat similar idea only- the girls were popping in buckets while croutching on tables in a classroom and it was splitscreen so you could see reactions from other women (I believe they had pooped too) and one woman had a pet parrot so whenever she hesitated or moved about in disgust, the bird fluttered around. They didn't highlight this scene a lot because, I'm guessing, they would have seen it as a distraction to the highlight of the pooping girls. The girl struggled to poop. It was real solid stuff which just goes to prove- Scat Girls go to Heaven.
