Last night on Keeping Up with the Kardashians, the girls' high-end clothing store Dash was vandalized during store hours by some crazy who tore up the clothing, threw a soft drink, and destroyed a mannequin. As a preventative measure, the sisters and their employees took a self-defense class, and somehow managed to make the methods they were taught sort of sexual. Then, when they got home, they demonstrated said sexual methods on stepdad Bruce Jener and things got a little...weird. Clip above.
