I played a B
When a musician makes a mistake and tries to act like it was totally on purpose and no one saw it coming.
'I played a B' he said, like he had planned it all along and no one had noticed the mistake.
'I played a B' she said, as if the audience had been waiting for that note and it was a surprise.
'I played a B' he said, while the conductor was still staring at him like he had just committed a crime.
