How Come there are never any pratical jokes being pulled when the guys are back in the barrack?  Almost every  Jarhead, Squid, Flyboy, or Grunt I have ever talk to has at least a handful of stories about joke being pulled in garrison.  those are good harmless (for the most part) laughs to blow of steam.  I haven't seen the guy fresh from boot sent for anything stupid like:

a box of grid squares.   spool of flight line.   blinker fluid.   squelch oil.  bateries for the prick E-7.  chemlihgt battiers.     B.A. 1100 N. (balloon)

Tango Romeo double Eco (tree)   metric cresent wrench.  left handed ax.    can of dehydrated H2O. 

none of that stuff.

so like I said why aren't they in the books that is just part of military life.

never heard of mail bouy
