oh boy... yours are much better than mine... but its one of those things i think, when formed up during inspection or what have you... that any remark the least bit funny will send at least one or two people chuckling down the line.
one of the best thus far for me was during inspection, our lt. decided to do it as opposed to mcpl or sgt...... he's doing 4 sec infront of me, and yanks a pen from a pvt's pocket.. obviously unimpressed it was exposed.
lt: pvt have you ever seen a wee pen?
pvt: a wee pen sir?
lt: WEEEEE! (as he tosses the pen over his shoulder into the air)
now it might not seem very funny here, but man it make half out platoon crack up on the spot.
i've heard various remarks while doing things, usually a course cpl or mcpl...
cpl: you people move like old people fuck!
cpl: you people are slower than the second coming of christ!
we had a good sgt give us a lecture on hygeine in the field... his favorite remark was
"if you are _____ you are dead"
usually it related to dirty, unclean... etc.
he made sure to tell us if we were in the field with him, and unwashed he would make sure we were dead
i'm sure I have more, can't think of them right now
