The military specification (Mil-Spec) for...
1. PIPE MANUFACTURE
1.1 All pipe is to be made of a long hole surrounded by metal or plastic.
1.2 All pipe is to be hollow throughout the entire length - do not use holes of different length than the pipe.
1.3 The internal diameter of the pipe must not exceed the overall diameter, otherwise the hole will be on the outside.
1.4 All pipe is to be supplied with nothing in the hole so that the water, steam or other stuff can be put inside at a later date.
1.5 All pipe should be supplied without rust; this can be more readilyapplied at the job site.
(Note: Some suppliers are now able to supply pre-rusted pipe. If available in your area, this product is recommended as it will save a great deal of time on the job.)
1.6 All pipe over 500ft (153m) in length should have the words "long pipe" clearly marked on each end so people will know it is a long pipe.
1.7 Pipe over two miles (3.2km) must also have the words "long pipe" painted on the middle so people will not have to walk the entire length of the pipe to determine whether or not it is a long or short pipe.
1.8 All pipe over 6" (152mm) in diameter must have the words "large pipe" painted on it so that it cannot be mistaken for a small pipe.
1.9 Flanges must be used on all pipe. Flanges must have holes for bolts quite separate from the big hole in the middle.
1.10 When ordering 90, 45 or 30 degree elbows, be sure to specify right or left hand, otherwise you will end up going the wrong way.
1.11 Be sure to specify to your supplier whether you want level, uphill, or downhill pipe. If you use downhill pipe for going uphill the water will flow the wrong way.

This time, I know where it came from, but I'll never tell, other than to say that, apparently, everyone I've ever known has been a smart-ass geek...
