See the doo-dad in the photo there at the left? I'm sure you've all seen something like it in public restrooms across the country. That little thingy sticking out to the left of the main, upright whats-it? Do you know what it is? I'll give you a hint, in case you're mystified. It performs the very same function as the little lever on the commode in your bathroom at your own home. When you push it down as far as it will go and then release it, the contents of whatever device to which it is attached (this handle thingy can be found on both the upright and seated versions commonly found in lavatories, what a swell idea!) are whooshed away, to be replaced with much cleaner dihydrogen monoxide. How cool is that? Use of this lever-type device reduces odor caused by the previously mentioned contents of the attached device.
Now that you know what that little thingy is for, please for the love of Pete, FLUSH THE &@#$ed TOILET WHEN YER DONE!
