That(Sherlock) is one of my favorite jokes that my late father loved to tell.
Like Reeg said. Jokes are a personal and arbitrary subject
Here’s another of my dad’s favorites...highly condensed.
A reporter was stopping people on the street and asking them what the most amazing invention of the 20th century was.
The first person replied that it was the jet airplane. Because it had made the world so much smaller.
The second said it was modern medicine because it had saved so many lives.
Finally he asked an old wino shuffling down the street.
The wino thought long and hard and finally replied “the thermos“
The reporter was surprised and asked him what is so amazing about the thermos?
“Well ,If you put something hot in it it keeps it hot.
But if you put something cold in it it keeps it cold.
How do it know?
