Q. How do you know the guy on the side of the highway with a flat tire
is a DEC Field Service Engineer?

A. He's swapping out all the tires to see which one is flat.

(or from net.jokes in 1981...

The way I heard it was:
How do you tell if a man with a flat tire is a DEC Field Service Rep?
Look in the trunk; if he's from DEC F.S. he'll have three spares with little
red tags on them and no jack.
