The owner of a musical instrument store summoned one of his staff who was overheard arguing with a customer. He asked her what they were arguing about. "She wanted a guitar, and I told her we didn't have one."
The boss said, "So she wanted a guitar, the customer is always right. Why did you give her a hard time?"
"Well, for starters, she was left-handed, so she wasn't right."
The symphony musicians had little confidence in the person brought in to be their new conductor. Their fears were realized at the very first rehearsal.
The cymbalist, realizing that the conductor did not know what he was doing, angrily clashed his instruments together during a delicate, soft passage.
The music stopped. The conductor, highly agitated, looked angrily around the orchestra, demanding, "All right! Who did that? Who did that?"
