How about a task loosely based on Jeremy Kyle/Jerry Springer It would be hilarious. Callum, being the psychologist sort of guy is the host- the large task room is turned into a mini studio- with a audience full of extras. Housemates are paired up (and for a joke are given fake awful joke teeth
) in relevant pairs for example Dexter and Charlie who have the problem of the 'Love Triangle'; someone confronting Gina on her snoring ect..
I think it'd be really funny - if Big Brother are satisfied housemates have created enough drama they pass the shopping task - £50 for each pairing.
