The remark by President Mahama generated lots of discussions in Ghana with many condemning him for his failure to empathise with the agitating Ghanaians.
Another Ghanaian, Anas Aremeyaw Anas, also made it into the list from his interview with the BBC over his judicial exposé.
Below is BBC’s best quotes of 2015:
1. “I belong to everybody and I belong to nobody”
Nigeria’s President Muhammadu Buhari on the day of his historic inauguration in May.
2. “We must change our lawless habits, our attitude to public office and public trust. We must change our unruly behaviour in schools, hospitals, market places, motor parks, on the roads, in homes and offices.
“To bring about change, we must change ourselves by being law-abiding citizens”
President Buhari said four months later on Nigeria’s independence day.
3. “The time for vision has come. I request our South African government to help us clean our land of lice. We need to remove all itching bedbugs and lay them bare in the sun.

South Africa’s Zulu King Goodwill Zwelithini, who denied that his comments in March fuelled xenophobic violence.

6. “I have seen more demonstrations and strikes in my first two years. I don’t think it can get worse. It is said that when you kill a goat and you frighten it with a knife, it doesn’t fear the knife because it is dead already. I have a dead-goat syndrome”

7. “This is surreal for me, I’m not going to lie, growing up in the dusty streets of South Africa, I never dreamed that I would one day have two things really: An indoor toilet and a job as host of the Daily Show.

South African comedian Trevor Noah as he made his debut hosting Comedy Central’s satirical news show in September.

Zimbabwe’s leader Robert Mugabe, mocking a US Supreme Court decision in June to legalise gay marriage.
9. “I love my work. But under our constitution, I cannot run again… I actually think I’m a pretty good president – I think if I ran I could win. But I can’t.
