Former Vice President Joe Biden in a new interview shared some of his favorite memes that joke about his relationship with former President Barack Obama, saying "in essence, they're all true."

"I feel good about it," Biden told NBC News of the memes. "All those memes, there are thousands of them out there, in essence, they're all true. We had that kind of relationship."

"My granddaughters and his daughters are each other's best friends. They vacation together. You know, it's family," Biden added, referring to the Obamas.

Biden said one of his favorite memes is one that shows him telling Obama that he hid the fake birth certificates in a drawer, a reference to the "birther" conspiracy theory that Obama was not born in the United States.

"A couple of ones I liked were ones where I was trying on Ray Bans and he's lying on the couch and I turn around and I said, 'Which ones do you like?' And he looks at me and says, 'Joe, Joe, come on, focus here,'" the former vice president told the news outlet.

Biden is currently promoting his new book, released this week, which focuses on the death of his son, Beau Biden.

In an interview released earlier this week, Biden expressed openness toward a presidential run in 2020, but said he is "not sure it's the appropriate thing" for him to do.
