In this rare behind-the-scenes glimpse, ABC News' Gio Benitez talked to presenter host John Crow at the Mega Millions headquarters in Atlanta, where the numbers for the 2018 $1.6 billion jackpot were drawn.

John said in the Good Morning America clip, “It’s exciting to know that I’m calling numbers that can change somebody’s life.”

Gio acknowledged that the balls in the draw barrels were not the actual ones used in the draw. “Those are in a safe, we can’t show it to you for security reasons,” he commented.

“But an auditor is going to be inspecting those balls before the drawing, and tonight those numbers could make someone very happy,” said Gio.
