I have an idea for BB3 you watch the 10 hosemates for 30 minutes after they go in and then evict one an hour later on first impressions alone.

Post ideas here

That'd be pretty good. Maybe if they started off with 11 people and only 10 bed. 30 mins after they go in they're individually called to the diary room and nominate 1 person. Person with the most votes goes before the day is over. Lol.
