The cadences were classic
"Throw some candy to the orphans
See them run and gather round.
Take your 40 millimeter
cut those little suckers down-
Cause napalm sticks to kids!"
Of course, the favorite was usually
"Hey young soldier, don't feel blue-
My recruiter was a liar too!"
However, I think that one probably dates back to Hannibal and the Alps.....
