You-Tube Afternoon 

After a long, exhausting week of work when co-workers need to relax a little bit and take a break from the daunting tasks piling atop their desk. Co-workers gather around one employee's computer screen, in their cubicle and search for funny youtube clips i.e. SNL Celebrity Jeopardy, etc.

D: What a week this has been!
K: OMG, I know! It's been crazy!
D: I think we need to have a You-Tube Afternoon to wind down from the week.
K: YES!

Piss Tube 

In Vietnam, there were two separate places to do bathroom chores. For a dump, there were shitters, most with multiple holes with 50 gallon drums underneath. The designated "shit-burner" would pull the drums out, add diesel oil and set on fire. If you just needed to pee, there were piss tubes around the area. Many were made by pounding old rocket tubes into the ground at an angle, and adding a piece of screen on the top end. In some of the more refined camps, a semicircle of tin would provide a bit of privacy. In my unit, the largest shitter (a 6-holer) was generally overfilled after dark for troops having extended "smoke breaks"

Hey new-boot, if you need to crap, the shitter is over there, if you just have to pee, you'll find several piss tubes throughout the area.
