I doubt it'll be done; in the manga, during the mock battle with the elder sisters, a stray round from M14 goes through Elle's skirt, causing her to fall to her knees and wet herself; anime ommitted the fluids.
Still, ya never know - maybe it's in the dvds.
Also... Thompson-sensei and Fujiko-sensei have definately aged well, compared to Garand-sensei, who's younger than them
Then again Garand-sensei looks to be an expy of R. Lee Emrey, aka Gunny Hartmann.
... right, I'm not sure how that whole "This is your rifle, love it" thing is going to turn out when the girls
are the rifles. ^^;;
Edit: Also, the Rifleman's Creed gets a bit more interesting of you recite it while thinking of the girls.
