This purportedly true anecdote was related to me last night, and I SMP.

Last Christmas season,  a women had an appointment with her GYN.  Just before leaving she "freshened up" a little with a spray of deodorant, so as not to offend.  In the examination room the nurse had her gown, and position herself on the examination table.  When the Dr. came in, he pulled up the gown and remarked, "Oh, how festive!"  It seems the woman had used her daughter's glitter spray by mistake. 

And Merrily supplies this one ...

A visiting minister waxed eloquence during the offertory. "Dear Lord," he 
began, with arms extended toward heaven and a rapturous look on his upturned
face. "Without you we are but dust..."
 
At that moment a little girl's voice asked, "Mom, what is butt dust?" 

If you have a good joke for our guys in Afghanistan, post it  here.
