There were three men in a tub. We don't know their names (just their professions), but we appreciate their commitment to water conservation. You can follow their lead by setting a timer for your showers. Your challenge this week is to see if you can shower in four minutes. Sure, showering a minute less is a surefire way to cut your water consumption, but 14 minutes (even with a low-flow showerhead) still uses more water than one that only lasts four. So, break out the hourglass or the kitchen timer and get it all done in under five minutes.
