four o'clock
`` The best trick of all was telling the time and doing questions in arithmetic . The Italian pulled his watch out of his pocket and showed it to the first pony , whose name was Diamond , and said , ` What time is it ? ' The pony looked at it , then scratched four times with his forefoot on the platform . The Italian said , ` Zat 's good four o'clock . But it 's a few minutes after four how many ? ' The pony scratched again five times . The Italian showed his watch to the audience , and said that it was just five minutes past four .
