If the title alone didn’t cure you of the urge to finish off those Christmas-feast leftovers, read the full article. 
Cloacina was the ancient Roman goddess of sewers. Think about that for a minute. To the Romans, the ability to take vile, disgusting wastewater and just get it the heck out of Rome was such a miraculous feat that they created a whole deity to watch over and protect the pipeline.

The whole idea of tap water from toilet water gives me a… sink-ing feeling.
Yes, I suppose if you think about it too much, you could feel drained.
Just thinking about it makes me feel flushed…
Better put a plug in it, then. Go bowl-ing instead.
I don’t think I’ll take the plunge, don’t want to faucet.
It’s mirrorly water, you know. Shower it who’s boss.
It looks like this comment thread is coming to a head, it’ll be trickle to think of something else to say.
Yeah, I think it’s nearly (shower) curtains for this one.
Looks like you recycled the sludge, though that’s appropriate considering the article. You said “shower” twice, so I’m tap-ping you on the shoulder about it… It’s OK, I’m tile-d of the thread anyway…
Shower and shower curtain — same word, different items. Don’t think you can brush me off so(ap) easily.
I grout you can figure out any more ones though, throw in the towel!
Don’t bet the farm on it, aloe still be going when the sun’s razor extinguished.
Vera good, so we’re going to dial in some zest-y soap puns?
Only conditionerly, you’ve got to draw the line and lav out something.
