I think we all know a refrigerator should always be plugged into the bottom outlet and a heating device into the top outlet for most efficiency.

I suppose the different colored caps on fire hydrants should be thrown into the mix.
I think that varies by department to some extent. There is a national standard but ...
Oakland Califorina used to have a different size hydrant connection but state law forced them to change after the Oakland hills fire killed 25 people and destroyed almost 3,000 homes in the city city. Only nearby fire departments had adapters so departments more then 50 miles away could not help.
San Francisco still uses a non standard 3 inch hydrant and some big high pressure, 300 PSI, hydrants downtown as well.

I suppose you could buy quilted paper and unroll it into two sheets and a layer of quilting to get three times as much use per roll.
