For all his machismo, Sam is a deeply insecure character, particularly when it comes to his brother, who's more successful, highly-educated, and flies on private jets. What is his brother's name?

As described on the Cheers fandom page: "Derek is the brother of Sam Malone. He is never seen, but he is said to have golden blonde hair, deep blue eyes, and an operatic voice. He can do trick pool shots, and he tap dances. He is an international lawyer and owns his own plane."
