Smelly little pink, white, or otherwise pastel bars that smell like mothballs added to urinals in hopes of making them smell prettier. (How'd you like to put "Urinal Cake Salesman" on your tax return?)

Alas, if you pee on a UC, it will atomize the spray, causing a part of it to splash back upon your person. Thus, the odor is merely directed out into society at large.
