Third podcast design

My last design is more of a sitcom, casual podcast episode. Even though the mood will be rather relaxed, I don't want to fall into all the inside jokes and awkward silences so the podcast will be scripted. It would be audio and last about 15-20mn.
I will have one or two friends as well as myself discuss stereotypes according to an agreed list. Since I have more time and will not need people to introduce themselves as in interviews, I can go into more aspects of teenage stereotypes. In particular, I'd like to discuss the way adults sometimes view teenagers - uncontrollable forces of nature, who must be excused if they do things wrong and never listened to when they do things right since they are hot-headed. I would like to have an adult come on the sitcom, but I don't know who I could ask.

Here are the subjects we will be talking about:

1. How teenagers are often viewed by adults
2. Why this stereotype originated, why it sometimes fits and sometimes doesn't
3. Stereotypes within teenagers - where do they come from?
4. How being considered a jock/nerd/prep/tomboy/geek/outcast might affect your life
5. Are these stereotypes ever useful? What kind of effect do they have?
   
6. What we can do to overcome them? Should we overcome them?
7. How may stereotypes abroad differ from stereotypes in typical high schools?
8. Which sort of stereotypes may disappear or emerge in the future?
   

I will write a somewhat long script, in order for the podcast to reach the time I intend. I think the hardest thing might simply be finding people to talk on the sitcom with. I can try getting the help of my family and exchanging "podcast" time with other students in my group, by helping them and then having them help me with my own podcast.
