If you get feces on your hands, a few wipes with paper towel is good enough.

Why do we need something fancier for a toilet?

I sure hope a few wipes with a paper towel is not good enough for most people who get feces on their hands

No water at all? You realize you're straight up eating your own shit when you have a sandwich afterwards, right?

I would’ve expected better sarcasm detection from this audience.

But, since jokes are best explained:

The opening assertion is one that mimics the toilet hygiene practices of many, but recasts it in a scenario that the reader is likely to find repugnant and evoke a reaction.

The second statement draws the reader’s attention back to the topic at hand, with that fresh strong feeling.

The reader may then make the connection that if “a few wipes with paper towel” is not good enough in scenario A, then the argument is that it is not enough in scenario B.

Others would downvote.
