Oh, demon alcohol
Alcohol, also known as Booze, is a liquid solvent commonly used to rinse out the insides of British actors. It also serves as a propellant mixture, capable of keeping television shows on the air for up to seven years at a time. Its third and most important function is as a disinfectant, for the purposes of killing off any pests or bugs that might cause trouble with the body.
