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.
