“He Called Me ‘Ken Jennings’” — A Jeopardy! Legend Shares a Touching Story About His Son on Live TV

It was a moment of unexpected tenderness on Good Morning America when Ken Jennings — the legendary Jeopardy! champion and current host — opened up about a sweet and humorous family memory. Promoting the upcoming third season of Celebrity Jeopardy!, Ken participated in a live segment where he fielded playful trivia questions. But one clue in particular brought back a poignant slice of the summer of 2004, when Ken was just a rising star in the world of quiz shows.

As GMA co-host Lara Spencer quizzed him, she posed the clue: “This is what your oldest son called you instead of ‘Dad’ the summer you were on Jeopardy!.” Ken couldn’t help but smile as he answered — it was “Ken Jennings.” His son Dylan, only a year old at the time, had picked up on the show’s signature opening announcement from Johnny Gilbert. Instead of “Daddy,” the toddler would address him by his full name: “Ken Jennings.”

“He was only a year old, and he called me ‘Ken Jennings’ all summer,” Ken recalled with a laugh, his voice carrying a mix of pride and nostalgia. “Like, that’s what the announcer said.”
