The host of a show titled "Death Penalty" would likely greet someone they're meeting for the first time with a darkly humorous and ominous introduction.

Greetings, welcome to Death Penalty! I am your host today. Call me the Grim Reaper, or the Master of Ceremony, or whatever suits your fancy. But remember, in this arena, I hold the power of life and death. I welcome you to our twisted little game where rules are made to be broken, and consequences are harsh. Are you ready to play?
