That one shows how unprepared people can be, I think if your going to do a skit and your unprepared, you should atleast have a good idea what your going to do. I once did a skit completly unprepared so the judges could judge(final judgeing) at a cosplay contest(chibi pa), and it was pretty good, not great but good. I was SNJ Naruto, I got a Inu Yasha group and we fought over ramen. I did the best with what I had, my ramen dissapred at the end of the skit, I miss my ramen T.T.
