 When he's telling an answer to a question, and he wanders off rhetorically to somewhere else, and nobody knows where he's going. As I remind you, on Thursday night, at one point, Joe Biden was asked a fairly simple question. He began to answer it. His answer wandered off into nowhere. And when he finally finished, and they turned to President Trump, President Trump said, I don't know what he just said, and I don't think he knows.
