Talk:Donald Trump vs Ebenezer Scrooge/Rap Meanings/@comment-1783865-20140108174957/@comment-24353761-20140111024027

The words "one" and "won" are homophones; they sound exactly the same. Homophones are the sources of many puns, knock-knock jokes and other attempts at humor, so the pun is that "Who won?" replaces "God bless us, every one!" at that very last word.

I can't really explain it any more clearly than that.
