Joe Biden zinged a man in Iowa who asked him how to save his marriage.

“My wife recently left me. She’s divorcing me. What can I do to get her back? What advice would you give someone like me to get her back?” the man asked the Democratic presidential candidate at a campaign event in North Liberty, Iowa.

“I’ll talk to you afterwards, OK? I’m happy to. I promise I’ll talk to you afterwards,” Biden, 77, told the man.

“Could we just get this out right now?” the man replied, to which Biden said, “No.”

The man continued talking, and members of the crowd began booing him to sit down.

“I’m beginning to see why your wife left you,” Biden quipped, prompting laughter from the crowd. “Sir, I promise you I’ll spend time with you afterwards.”

Biden has been married twice. His first wife, Neilia, died in a car crash in 1972. The crash also killed his daughter Naomi. He married his second wife, Jill, in 1977.

The man agreed to speak after the event and sat down. He appeared to be a Jason Selvig, a member of the comedy duo The Good Liars. The duo interrupted an Andrew Yang campaign event a day earlier, asking for money out of the candidate's wallet and asked if he was a robot. After the Biden event, they showed up at an Elizabeth Warren event, where one of the men proposed to the candidate.
