I say it's the hardest working because in those 20 years it was the faucet that saw the grimiest of hands, and it was the first place of rest when anyone ran inside in a hurry, if you know what I mean. PU!
Hands working hard in the garage, out in the yard, and the faucet that six kids delivered their dirtiest paws too.
Oh, and it saw animal paws as well.
My family put the mud in mudroom.
