And Jeremy Beadle - remember the woman who thought aliens were in her back garden and she asked them if they wanted a cup of tea? Or the bloke who's van they swapped over and ran it into the Thames. He was going ape. These were just well executed pranks, and they went on national tv afterwards to be interviewed by Beadle on the show. Didn't hear of anyone on that show committing suicide. Like I said earlier and most of the comments, the nurse must have been troubled by a lot of things!
