But then, as I was showering, I thought why capture the girls? Why not take the same concept but capture their undies instead. This reminded me of Happosai from Ranma 1/2. You are a dirty, short, old man. You sneak around the city and grab bras and undies from right under them. Sounds more fun to me. Ha.
