The things that make me laugh are varied but all linked by the connective tissues of irony and/or plausibility/implausibility.

Could this happen?

If it can happen – how humiliating would it be for everyone I know to see it happen to me?

If it isn’t likely to happen is the pay-off (the humiliation factor) so great that it is worth pushing the envelop of statistical probability to try to reach the point where it IS likely to happen?

Is it ironic?

If it happened in front of people would they instinctively think that I deserve this kind of humiliation?

If it didn’t happen in front of people, would the think it so humiliating that they would either be willing to believe it happened because it would please them or at least pitch it up against my track record of humiliating myself publicly to think “…yeah – he really did do that…”?

I guess what I’m saying is that the thing that makes me laugh is humiliating myself. That explains a lot about the past 40 years.
