The lovely Emma Stone joined Conan O'Brien on his late night chat show recently to promote her latest film The Irrational Man, directed by Woody Allen.

While there she told Conan about her favourite Woody Allen story whilst working with him, which was a conversation whereby he asked her to explain Twitter to her.

As part of Emma's explanation, she quotes a Tweet to Woody which turns out to be one of his classic movie lines, the famous "Tragedy plus time equals comedy" from his 1989 film Crimes and Misdemeanors.

And well....Emma explains it better!
