Ironic Karma Inc.

So Paul and wife Wendy work for the same children's charity, and both take sick leave to deal with work-related stress. Visiting friends in Australia, they hit the beach one day and a bunch of idiot children go for a swim in the shark-infested waters. Paul grabs a shark by the tail to prevent an attack, a television news crew happens to film the whole thing, Paul and Wendy return home to Britain and find a letter waiting for them ... If I hadn't gone in to save the kids that day my wife and I would still have a job.
