On Wednesday’s episode, Damon and Jennings won the $1 million prize in support of Damon’s charity Water.org, which is focused on universal access to clean water. They won with the question “Which of these words is used to describe one of the most beautiful auditory effects on Earth, the sound made by the leaves of trees when wind blows through them?” The correct answer, which Jennings knew, was “susurrus.”

The solid showing made “Who Wants To Be A Millionaire” the top program of the night for the second week in a row; “Millionaire” also maintained its same adults 18-49 rating (0.38) from its season premiere the previous week.

“Who Wants To Be A Millionaire” was ahead of the night’s No. 2 broadcast program, CBS’s “Big Brother” (3.02 million), by 48% (3.02 million). ABC won the night among broadcast networks in total viewers (2.86 million).
