I saw this the other day at a salvage shop, where we were looking for some decorative items and doors we might use at our house:
An electric fence charger. Really.
You have to love the key phrase: "Shocks through wet weeds." I would imagine so.
(Side note: this is from Montgomery Ward, which - along with Sears - was where we did much of our department store shopping when I was growing up. Affectionately known as "Monkey Ward," the company went out of the retail store business in 2001, but it (sort of) lives on as an online retail company.)
