[a derogatory pun on ‘field service’] The field service organization of any hardware manufacturer, but originally DEC. There is an entire genre of jokes about field circus engineers:
Q:�How�can�you�recognize�a�field�circus�engineer
���with�a�flat�tire?
A:�He's�changing�one�tire�at�a�time�to�see�which�one�is�flat.
Q:�How�can�you�recognize�a�field�circus�engineer
���who�is�out�of�gas?
A:�He's�changing�one�tire�at�a�time�to�see�which�one�is�flat.
Q:�How�can�you�tell�it's�your�field�circus�engineer?
A:�The�spare�is�flat,�too.
[See Easter egging for additional insight on these jokes.]
There is also the ‘Field Circus Cheer’ (from the old plan file for DEC on MIT-AI):
Maynard!�Maynard!
Don't�mess�with�us!
We're�mean�and�we're�tough!
If�you�get�us�confused
We'll�screw�up�your�stuff.
(DEC's service HQ, still extant under the HP regime, is located in Maynard, Massachusetts.)
