Milo Ventimiglia, who currently stars as a '70s-era dad to three on This Is Us, visited Ellen DeGeneres to talk about the show. And, like Justin Bieber before him, he participated in the great tradition of showing off your muscles on daytime television.

"His adopted father literally carried him on his back and showed him that he will be there for his son for his entire life," explained Ventimiglia. "And so we did a bunch of push-ups.”
