Joe Biden explained why he advises young men to marry into families with 5 or more daughters.

“I say to every young man thinking of getting married, marry into a family of five or more daughters. I did. My wife is the oldest of 5 sisters,” Biden said during a speech on Tuesday in Nashua, New Hampshire.

“You know why? One of them will always love you. Not the same one. One of them is always going to be on your side. That’s the biggest advantage of marrying into 5 daughters,” he added.

Biden’s speech was about the PACT Act, which covers health care for veterans exposed to toxins from burn pits.
