Ok, this is funny.
A movie theater in London decided to have a little fun with the whole Best Picture Oscar debacle, where "La La Land" was mistakenly announced as the winner, when it was actually "Moonlight".
They pranked a theater full of people who had paid to see "Moonlight" by showing "La La Land" instead. No, theater goers didn't have to sit through the entire wrong movie - only about 20 seconds actually, jusssst enough for it to be effective.
The audience reportedly got the joke and applauded at the well timed prank, before settling in to watch the movie they actually came to see, Best Picture winner "Moonlight."
