After discussing his verbal slip-ups with Fox News’s Chris Wallace, Joe Biden made another one by thanking “Chuck” for the interview.

Biden, who has frequently flubbed words and phrases on the campaign trail, was asked by the Fox News Sunday host about some of the recent times he misspoke, including when he discussed being a Senate candidate and said to “vote for the other Biden” if people don’t like what they see. At the end of the interview, Wallace thanked Biden for taking the time to speak with him.
