“You won’t believe this,” Is the way someone began a lengthy (I’m talking from 11:14-12:08) conversation, ah, sorry, that’s wrong, monologue at me. At 12:08 he asked what I thought of his tale.
“I dunno. You lost me at, ‘You won’t believe. . .’ because if I’m not going to believe something why listen?”
Let me say for the record, I heard his next couple of dozen words loud and clear.
