Kevin Hart Gets 'Pissed Off' During 'The Late Show With Stephen Colbert'

Funny man Kevin Hart swung by The Late Show With Stephen Colbert. While talking about staying positive, the host Stephen Colbert said something that left the comedian feeling negative. Hart attributes much of his personal and professional success to staying positive. According to Hart, negativity is a waste of energy. The comedian said, "You know how much time it takes to hold an attitude and grudge? That's time and energy. The time it takes you to go 'I don't like that person' and keep that in you is a lot of time that can be devoted to being positive." Colbert agreed with film star and in fact shared a similar Nelson Mandela quote, "Holding a grudge is like drinking poison and thinking it will kill the other person." Hart thought the quote was "amazing" but he admitted "I'm pissed off." Hart went on to explain why he was so frustrated saying, "That was a real bad moment for me as a black man." Colbert tried comforting Hart saying, "You can't know everything every black man said." But Hart replied, "No, but you said, 'You know what Nelson Mandela said--' and I was, like, oh, sh*t, I didn't know."
