Another maestro-baiting story about an unnamed conductor:

Rehearsing an orchestra, the conductor stops them after a complex wind chord and glares at the second oboist: “You there—that note was out of tune!”

Unabashed, the oboist retorts, “OK then maestro… so was it sharp, or was it flat?”

Floundering, the conductor goes, “It was sooo out of tune, I couldn’t tell!”
