(NEWSER)  – Walter Cavanagh of Santa Clara, Calif., holds the Guinness Book of World Records title of "Mr. Plastic Fantastic," and Money revisited his story earlier this week.

As it recounts, Cavanagh has 1,497 valid credit cards, adding up to $1.7 million in available credit. The wild stats don't end there: His custom wallet, the world's longest, stretches 250 feet, weighs 38 pounds, and can hold only 800 of his many cards, not that he carries them around: The Los Angeles Times reported in a 2004 profile that all but one (which he uses and pays off in full in each month, giving him nearly perfect credit) are kept in a safe-deposit box. Cavanagh's card collection started as "silly bet" with a friend nearly half a century ago. Whoever collected the most cards by the end of the year would win a dinner. The final score: 143-138 in Cavanagh's favor.
