The most famous phreak of all time, who discovered that the whistles that came in boxes of Captain Crunch cereal emitted perfect 2600 Hz tones. 2600Hz was the frequency used by Bell's switching systems to indicate a trunk being freed. By sending 2600Hz after making a call to a WATs line after they hung up, you could trick the phone network into giving you another dial tone, on which you are not charged. You could then send MF tones to dial your second (free) call. Steve Wozniac, co-founder of apple computer supposedly used this trick to prank the pope without paying anything or being at all traceable. None of this stuff works anymore, of course.
Captain Crunch whistles are now sold out of the back of 2600 magazines for $99. But they don't actually do anything anymore.

2) A popular name for LSD in the 1960s. It was called this because acid was commonly sold on sugar cubes and Captain Crunch cereal in the late 1960s and early 1970s.

Perhaps the greatest creation mankind has ever achieved, alongside sliced bread. A fruity cereal with a absolute savage, badass captain on the cover of the box. Consumers usually eat Captain Crunch with milk, although more die-hard fans will tend to eat right out of the box. Legend has it that if you eat a whole box of Captain Crunch alone in a dark room, the Captain himself will visit you in your dreams that night.
