Bill Clinton Smiles and Laughs Looking Over Epstein Files Photo, on Video

Bill Clinton couldn't take his eyes off a photo from the Epstein Files ... and it looks like the throwback made him smile and laugh.

Check out this clip from the former president's hours-long deposition last week ... he's grinning and chuckling as he appears to look at an old photo.

Clinton was grilled about a photo from the Epstein Files showing him in a hot tub with a redacted person next to him ... and he explained his story behind that snap -- though it's not clear in this video which photo Clinton is having a laugh over.

The former president's attorney tried to snatch the photo from Clinton, but it looks like he kept his eyes on it, winning it back in a brief tug-of-war ... and they seemed to share a moment.

Clinton says he was unaware of Epstein's criminal conduct until the convicted sex offender got busted in 2008 in Florida ... he insists he would have turned Epstein in earlier if he "had any inkling" of Epstein's crimes ... but whatever was on the page looks like it had Clinton going down memory lane.
