Educational for me however:
Rule 1) It's okay to make the audience think a little, but don't give them a knot in their stomach for four minutes, until you let them relax...especially if they're a nice Christian audience; they will worry with and for you. The pagans might enjoy you floundering, but you will give the Christians empathetic diarrhea.
Rule 2) Don't punctuate every punchline with "sooooo..."
But overall, we made some money; it's all about the money...and the British.
