This year, Ben Affleck says he is leaving the Christmas shopping to wife Jen Garner - and with good reason.

He says he's pathetic when it comes to picking out presents.

"My wife is so capable and because I'm less so, she does a lot of that work, and I kind of root her on," he says on The Ellen DeGeneres Show Tuesday (check your local listings). "I'm encouraging."

When it comes to shopping, The Town star, 38, says, "It takes her as much energy and effort to buy like the 20 gifts we're going to buy other people, as it does to buy her gift. I spend the whole time, fretting about that and being nervous and hoping she likes that. And then I end up at like CVS on the 24th being like, 'Maybe she'd like a little Godzilla that goes around.'"

Affleck may need to brush up on his shopping skills fast: His daughter, Violet, turns 5 Dec. 1.
