I was actually kind of surprised that this was 'that episode'! I thought it was hilarious, and I could easily relisten to it, even with all of the disgusting content. If I'd been reading the text I was hearing or (gah) looking at some kind of image of the content in question, I'd probably have different feelings, but as it was, I was mostly just entertained by the suffering of the readers.
On my personal scale of horrifying fplus episodes, I'd say it's slightly less disgusting than the adult babies episode was (but only slightly).
