AlphaGam,
I think the main reason why we keep the same skit (Theta Night Live here
) is because it already takes such a huge effort just to get the same skit together (with different girls) each year, let alone make up an entirely new concept. SO much work goes into preparing for the skit, even though they're relatively short. We're talking skit practices starting MONTHS before rush week, for essentially the same skit we put on the previous year! It's already too much work as it is. And besides, it's not like the rushees have ever seen the skits before even if we all have.
