Hot-shot Jokes

When a young hot-shot conductor was making his debut at the Met, he showed the jaded and skeptical orchestra how well he knew the music by singing all parts of the Lucia sextet during rehearsal.
Afterwards, one musician was overheard whispering to the other, impressed, "Well, this kid really knows his stuff!"
The other replied, " *I* don't think he is so hot - did you notice how flat his high E was at the end?"
