Does anyone genuinely believe there was a sinister motive behind the prank call. I doubt for one minute they ever expected to get through and once they were they just got themselves deeper and deeper. As for the whoopee cushion analogy, what if grandma had a heart attack! As I said earlier, you wouldn't expect that to be the outcome. If anyone is to blame it is the management of the hospital who, having such a high profile patient, should have had protocols in place and particular make staff aware of the likelihood of fake calls and the like.
