To glee or not to glee

I watch Glee. There. I said it. I feel so much better. Now that the burden is lifted off my shoulders. I am entranced by the teen drama, Mr. Shuster’s hair, and Sue’s endless battle to destroy the glee club.

I only have a few questions-

1. How do you get a group of people to go into a random music number?

2. Will my hair just instantly get pretty the moment I join or will it take some time?

3. Where does Sue get those sexy tracksuits?

4. Will Mr. Shuster ever get laid?
