There are always a lot of joke circling around in england about tragic current news headlines, Madeline Mccann jokes, a young girl who went missing in portugal, spring to mind.(hide and seek champion of europe) Also there were a load of Diana jokes back in the day...
edit: just read the jade goodie thing and it reminded me what my friend said to me when she was still alive, he said "i told the guys at work to join in on a sweepstake where we each put £5 in and pick a day, whoever picks the right day of the week she dies wins. They all thought it was terrible, but I explained, this way I only want her to die one day of the week and thats a massive improvement on before!" I thought that was pretty funny.
