I was highly amused to come across an advertisement on YouTube for something called Poo-Pourri. It's a deodorizing spray that one uses in one's toilet before a No. 2, which the manufacturers claim will 'seal' the resultant odor beneath an impermeable layer on top of the water. I've no idea whether or not it works, but they offer a money-back guarantee, so I daresay it can't be too bad.
Here's the first advertisement that I saw.
Next, one directed at men.
And finally, a blooper and out-take reel.
I'm guessing this might sell well to churches. After all, they're all about the odor of sanctity, so why not the non-odor of sanitation while they're at it?
