Being an intel geek, spying has fascinated me for ages. I remember the Walker case, and it's been reviewed for ages. Talk about a cluster f^&*. 

John Anthony Walker Jr. Spy Case

In 1985, dubbed by the press as the “Year of the Spy,” former U.S. Navy warrant officer John Anthony Walker Jr. was arrested for selling U.S. secrets to the Soviet Union.

Walker’s espionage began in 1967 when he walked into the Soviet Embassy in Washington, D.C., with material that would allow the Soviets to read encrypted naval messages.

During Walker’s time as an active spy, the Soviets went as far as to give him a device that, when placed on top of a cryptographic machine, would record the rotor settings, thus allowing the Soviets to decipher all communication sent using the machines.

Nuclear engineer, wife who tried to sell Navy secrets in peanut butter sandwich sentenced for espionage

MARTINSBURG, W.Va. — A former Navy nuclear engineer and his wife, who were accused of trying to sell military secrets using a peanut butter sandwich, found out how long they will spend in prison Wednesday.

A judge sentenced Jonathan Toebbe, 44, of Annapolis to 19 years and 4 months. He also ordered Toebbe to pay a fine of $47,500.

His wife, Diana Toebbe, 46, received a longer sentence: 21 years and 10 months. The judge ordered her to pay $50,000.

...“If not for the remarkable efforts of FBI agents, the sensitive data stolen by Mr. Toebbe could have ended up in the hands of an adversary of the United States and put the safety of our military and our nation at risk,” said U.S. William Attorney Ihlenfeld in a news release, issued the day of the sentencing. “The FBI keeps American citizens safe from enemies both foreign and domestic and this case is an excellent reminder of their important work.”

Peanut better. Sandy Burger was caught trying to sneak classified data out in his socks. Another example of how not to do it. But as I've said countless times, I don't knock stupid people. They insure I have a job.  :<)
