A Bulgarian professor has promised students A grades if they write about Angelina Jolie's boobs and buy a copy of his new book.
Professor Stefan Karastoyanov, of the Geology and Geography Department of Sofia University, made the promise as a protest after he was not paid for three months because of cash problems.
He said: "If they write about Angelina Jolie's boobs and buy my book they'll get an A."
So far 80 of the 120 students sitting his classes have ordered his book
