Base this just upon song choice/editing/clips used/etc. not because you hated a housemate *cough* Charley *cough*
I'd have to say the best was Gerry's. Such a fitting song! Surprised that that Depeche Mode song didn't pop into my head for him sooner.
The worst, was definitely David's. It seems like he was such a boring guy, that they had to salvage all the clips they could in order to make a 2 minute best bits video.
Who do you think has had the best/worst Best Bits this series thus far?
