I've heard stories about Parris Island sand fleas, if you swat one you have to give it a funeral? Thats what my young marines drill instructor told us.
And you better check the sex of that little stinker to, There IS a quiz at the end.

It's funny now, but try standing perfectly still at attention while something 1/4 inch long takes a stroll around in your ear then comes down and sinks its 2 inch long teeth into you left nostril. Try that for say, 5 minutes , They do not supply a totally bug house smiley here or I would use it. Any one who can do that has SELF DISCIPLINE ! Some times they will land on you nose and walk around like a dog looking for somewhere to crap, Then when they are positioned right exactly between your eyes, on the tip of your nose, They will look you right square in the eye, smile an evil little bug smile, and chomp. And the little SOB's will fly off just as you are dismissed from formation. I swear to God those little ba$*ards recognize the commands better than some of the Recruits. God I HATE SAND FLEAS.
