Wondering About Ass Gaskets

I Long For A Mundane Existence Sometimes...

So, you know those paper Ass Gaskets in public toilets? The ones you lay on the seat to keep the AIDS virii and pubic lice from crawling up into your buttcrack?

Are those flushable?

I know, you can probably get away with one, 'cause they're thin, but if the hygiene of the toilet requires a thick stack, I'm just wondering what'll happen on the flush.

Anyway, any amateur plumbers out there, feel free to comment.
