Suffice to say, the last thing Jon has to say to Desmond is "you're the nicest person I've ever met".
Desmond Tutu is, besides a Peace Nobel Prize recipient and veteran from the apartheid jails, an archbishop emeritus of the Anglican Church of South Africa. He pushed the church there through the apartheid years and went on to chair the South Africa Truth and Reconciliation Commission, which looked into the horrors and crimes during the apartheid years from a perspective of forgiveness and healing.
