There are actually passages in the Bible that speak negatively of joking and humor. I can't recall exactly where they are - maybe in Proverbs or Ecclesiastes - but the Bible does not approve of humor. That explains why there are no funny passages. All references to humor are portrayed in a negative light, associated with ridiculers and foolish men "in want of heart".
Jesus never cracked a joke. The closest the Bible comes to humor are passages that speak of God laughing at the demise of the wicked and Elijah ridiculing the prophets of Baal by suggesting to them that their god isn't answering them because he's busy in the toilet. There is no harmless, light-hearted humor purely as entertainment.
