Gordon Ramsay's Kitchen Nightmare

This joke plays on Gordon Ramsay's fiery temper and cooking show persona. The punchline makes a dark reference to the Holocaust by comparing undercooked food to the people who were killed in the concentration camp ovens, stating they're so undercooked they're still alive and have time to write diaries. It's a morbid combination of Ramsay's typical kitchen insults with a disturbing historical event.
