The BBC

The BBC is a conspiracy set up by Doccy Who to convince humans that they are not real and merely the convoluted imaginations of various writers. Unfortunately, this joke got out of control and now holds serious power on both Earth and what’s left of Gallifrey, forcing people to pay their TV licenses, else they get killed
Various attempts have been made to stop the BBC and all have failed. Romano Doctor don't even think about it and Sam Master are both known to have a history with this conspiracy.
