One of the feistiest exchanges in the independence debate came as Alistair Darling pushed Alex Salmond for his "plan B" if Scotland doesn't get to keep the pound upon leaving the union.
Unhappy with his first answer in which Salmond attempted to quote his opponent, the former chancellor asked the SNP leader to "contemplate for just one minute that you might be wrong".
Mr Salmond refused to contemplate the loss of the pound as he raised his voice to be heard above shouts from the audience.
