Former US president Barack Obama stole the show at the recent Nelson Mandela Annual Lecture in Johannesburg. Speaking of the great work done by Madiba, he also noted serious issues which continue to plague the globe, such as propaganda, sexism and racial and religious discrimination.

Although his speech highlighted serious issues, Obama was not shy to have a little fun. He clapped back at President Cyril Ramaphosa, who made fun of his dance moves, and couldn't help blushing when the crowd chanted, "Yes, we can!" a slogan made popular during his first run as president. Those attending praised Obama's skills as an orator.

Here are five quotes from Obama's speech that were just too lit to ignore.

Obama might have made a number of his fans tear up with this one, sharing the reach of Mandela's determination during his struggle against apartheid. 

The former president held no punches when referring to presidential successor, Donald Trump. Obama threw this jab referring to Trump and his administration at large who have refuted climate change.

Obama has many icons to who he looks up and this vision of freedom is based on not only that of Mandela but also Mahatma Gandhi, Martin Luther King and Abraham Lincoln, who were proof of the unity and freedom he believes in.

Another jab at the rise of Donald Trump, Obama spoke out about how access to information breeds a number of difficulties.

Obama shared his thoughts on what it would take for individuals to fight for what they felt was right.
