Vice President Joe Biden accidentally phoned the wrong Marty Walsh to congratulate him on his win as Boston's next mayor.

As Marty Walsh watched his namesake celebrate becoming the mayor of Boston on television at home, he was struck with a funny thought. Turning to his wife, he chucked, "I bet it would be funny if I got a call tonight from the White House."

According to CNN, the phone rang ten minutes later. A White House operator informed Walsh, a former political consultant and Edward Kennedy staffer, that he had a call coming from Capitol Hill. Walsh began to tell the operator that they'd reached the wrong Walsh, but the line clicked over before he could finish. A Washington area code blinked on his phone, and the veep's jolly voice came rolling in.

"Son of a gun, Marty!" Biden said, thinking that he'd reached former state representative now-mayor-elect Marty Walsh. "You did it."

Walsh told Biden that he'd gotten the wrong guy. Biden laughed, and Walsh gave him the correct number for mayor-elect Walsh.

"We've had this for the past 20 years happening back and forth," former Kennedy aide Walsh told the State House News Service. "Marty tells a funny story from 2006 when Kennedy thanked me from the stage and his mother thought it was for him."

Biden wasn't the only one to make an incorrect call of congratulations - mayor of Minneapolis and vice chairman of the Democratic National Committee R.T. Rybak also slipped up, as did DNC Chairwoman Rep. Debbie Wasserman Schultz. They left voicemails for the wrong Walsh, but the former aide was not bothered.

"It's an honest mistake," he told CNN.
