“If you want to make God laugh,” they say, “tell Him your plans.”
Of course, if you do want to make God laugh, you’re probably religious and more a little over-confident, and need to consider just what kind of God you’re dealing with before developing your set.
Number 1) Is He Existent? Don’t both trying to make any non-existent Gods laugh. It’s your own time you’ll be wasting, not His.
Number 2) Is He Omniscient? If so, I’ll wager He’s heard it, whatever the joke, however, if also Omnipotent and So Inclined, He may be able to laugh at jokes He already knows. This may also require Him to be a Personal and Active God, not to mention Personable (which I haven’t, OK?), and much may hinge on the way you tell ‘em.
Number 3) Is He a God who allows humanity Free Will? If the Universe in Deterministic and Pre-ordained it’s possible God will already know the outcome of your life (not to mention your comedy routine about it, which I have mentioned, to be honest, but only in parentheses) and may thus find your plans amusing.
If He’s one of those laissez-faire, leave it all down to you Gods, then He may have no idea how things will turn out for you and may thus fail to appreciate any possibly irony, unless He’s, as mentioned before, Omnipotent and/or Omniscient.
It goes with out saying that if Omnipotent He can also be Omniscient as required (obviously it hasn’t gone without saying just now, but it could have done).
When I was making my list of "things that could possibly go wrong" before, I neglected to count the barbecue being cancelled due to ill health as one of them, which is obviously far far worse than any of the scenarios I’d come up with in my head, and I hope all works out well.
That’ll teach me.
