Gaz was tired after a bullshit mission, it went successful but, it was long and tiring. Even worse Price assigned him with cleaning the helicopter after. Gaz reluctantly agreed, so here he is, on the helicopter cleaning He assumed he was alone as he started singing along with a song that he was listening to as he sung Mrs if you got bumper than twerk it, Mrs if you got a bumper then shake it. Embrace it. Gaz sung quietly his British accent can be heard as he did so.
