Team Lisa - David the dumbest HM ever!
 

Is he the dumbest BB housemate? You would have thought after coming in halfway that he would know you stick with Lisa and you are going to go. He was even warned by Tom. And Lisa after pumping him up, is just sitting cooly while david argues with Bea.

At least halfwit stood up for who he thought is his friend, while Lisa was just sitting watching the whole thing.
