Some people use humour to deal with trauma, I was in an intesive coranary unit in Kent and as people were brought in, we would have bets (no moey involved) who would and who wouldn't make it.

That and humour was the only way we had to deal with the fact that all 20 odd people in the ward had nearly died

I stopped when one of my jokes nearly killed the guy in the bed next to me (yes that bad)

When I returned home there was a car battery with jump leads on my doorstep, I found it hillarious my girlfriend didn't

Humour at the right time and in the right place, within minutes of the WTC happening I was recieving text messages and amongst them was a bannana boat / Bin Laden song that within an hour of it happening.

I would not think of reciting any of them. 6,000 wouldn't apreciate it and neither would their families
