acronym for Mutual Assured Destruction, a theory that states that a nation wouldn't begin a nuclear war because the opposing nation would destroy them in retaliation.
MAD may very well have saved all our asses from a nuclear holocaust on several occasions.

Madness is not a blurring or distortion of reality.. It's a sudden extreme clarity of things, unaffected by feelings or emotions"

Recently acquired by DC Comics, it's the best humor magazine EVER. Sure, there's a handful of commercial advertisements in its pages nowadays, but who cares about that?

Features content such as movie/TV show satires, Spy Vs. Spy, offbeat comic strips, etc. MAD's mascot since its inception, Alfred E. Neuman, is on every cover in some humorous fashion.

The magazine has also spun-off a fairly good TV series, "Mad TV," which airs in reruns on Comedy Central. Basically, Saturday Night Live on steroids. ;-)
Over the years, MAD has driven its competitor, CRACKED, into the dust.
