Lags' Guild

In the Discworld Thieves' Guild Yearbook and Diary 2002, it is revealed that this is the Guild that looks after the interests of professional prisoners. Its head is Joe "Lifer" Bushyhead. As part of Thieves' Guild training, apprentice Thieves are encouraged to join this Guild, should the worst come to the worst and they end up being persecuted for their beliefs by an oppressive State. (ie, they believed they'd never see the inside of the Tanty).

It is not known whether, as a Guild president, Mr Bushyhead attends City Council meetings as an advisor to the Patrician.
