This report from from the UN end-of-the-year press conference is mildly amusing:

...James Bone, New York correspondent of The Times... questioned Mr Annan about a Mercedes jeep that his son, Kojo, imported into Ghana using his father’s diplomatic immunity to avoid taxes.

“I think you’re being very cheeky,” [Annan] exclaimed, and continued: “Listen, James Bone, you’ve been behaving like an overgrown schoolboy in this room for many, many months and years. You are an embarrassment to your colleagues and to your profession. Please stop misbehaving.”
