When Journey Blue told the people who were going inside the molecular nanoscaler not to hold their breaths as the nanoscaler engaged, the Twelfth Doctor compared what would happen to a person that did hold their breath to lasagna that was microwaved without the film on top of the dish being pricked first. Clara Oswald said that the lasagna would explode, and the Doctor responded, "Don't be lasagna." (TV: Into the Dalek)
