'Dancing Man': 'I still have to pinch myself'
Sean O'Brien became the subject of online bullying after photos of him dancing were posted on the internet with the caption: "Spotted this specimen trying to dance the other week. He stopped when he saw us laughing."
Sean subsequently became known as 'Dancing Man' after a Twitter campaign was launched to find out who he was and to support him.
He was invited to Los Angeles where he partied with celebrities, and threw the first pitch at an LA Dodgers game.
Now a documentary has been made about him.
Sean, and one of the documentary makers, Katy Dolle, spoke to BBC Breakfast.
