Some kind of a sad story ...

Life event, it was 20 years of commercials a penny back.
My friend (now - a successful fashion columnist) moonlighted as a cleaner at the Pushkin Museum.
And once, at work, a friend tells a famous anecdote:

"There is a moment of passing the sandbox, and hears a boy says to another:
"You know what ment differs from the ass?
Cop grabs his ear: "Well, what, brat?»
 - Oh, uncle, nothing, nothing! ..
 - That's the same! & Quot;

While she says it all, passes by a police officer from the protection of the museum.
Hearing anecdote, asks:
"And what is actually different?! ..»
"Nothing! .." - Responds with downcast eyes, friend.
"Yeah," said the policeman and leaves.
