To start with, this is my new idea on television show.

A quiz program - you invite the wrong participants.

For example,
you invite men above 60 and ask questions about teenagers.
you invite men and ask questions about women's apparel, cosmetics, sizes etc.
You invite women and ask questions about men which are obvious to men, but not so for women.

I guess this will create lots of fun. Audience will love someone else making a moron of himself on the screen. Add spice by inviting some celebreties.
