I'd say 'Gun Ed' works as a nice addendum to Sex Ed..
as in... ' You touch my daughter, and I will teach you about guns. My gun. Ill also teach you about that quarry pond in the back of my property. '
thats pretty much how my FIL gave me a sex-ed class while the future wife and I were in High School- except his lesson was ' 17 years ago I brought this baby home from the hospital. She was a perfect, beautiful baby and is still my baby today. If in nine months or so, she can't..you know.. button her coat... Ill F***in' kill you, and no one will ever find you. Have a nice night at the prom. '
BTW, My FIL owned a roofing business before he retired. And several guns. He could have made that happen. That quote is probably verbatum, as it is seared-- SEARED into my memory...
I still feel a little odd when we bring the three grandkids by to visit....
