'Hi Dad': Watch Lester Holt and son's sweet on-air moment

"NBC's Lester Holt is here with a preview of the newscast,'' Stefan said. "Hi, Dad."

The sweet moment came when Stefan filled in for NBC affiliate WMAQ's 5 p.m. broadcast instead of anchoring his usual morning program.

"I've got to check my watch, I thought this was the morning,'' Lester joked. "Good to see you Stefan, proud of you."
