All good answers and points Dannielle.
I had a boss who used to tell intense/angry people with a chuckle, "Hey, it's only government work..." which I initially thought ran contrary to our values and pride in our work... but it was effective at diffusing many hotheads. I guess it was a play on the old "good enough for govt work", which I am vehemently against (govt work is more important than other work, not less!!) but his twist on it did seem to work.
Maybe a twist on his phrase could work?... "It's only paperwork, let's go get a coffee", or such...
