Usually, they tend to use the title of 'barrister'. Pretty impressive occupation coming from a nation where the national currency is based on firewood.
I had a whole collection of them - I'm in IS so EVERYONE forwards theirs to me to find out what they should do about it. My personal favorite was the guy who came right out and admitted embezzling money, and asked for help to launder it.
Their national currency is based on firewood? That's news to me ... Need some Nigerian wood?
