A building where I take a class has low flow toilets. They have the amount of water squeezed down so low that it sometimes takes 3 flushes to make the paper go down.
I left out the Dave Berry quote on low-flow toilets:
“They work fine for one type of bodily function, which, in the interest of decency, I will refer to here only by the euphemistic term ‘No. 1.’ But many of the new toilets do a very poor job of handling “acts of Congress,” if you get my drift.”
