'The Fantasticks' earned its investors a 24,000% return ... and counting

This week, the off-Broadway musical The Fantasticks will reach its 50th anniversary. The show, a valentine to young love requiring no more props than a stick, a sheet, and some confetti, is the longest-running musical of all time. That unprecedented record isn't the only miracle: Its original backers have scored, too. So far, they have earned nearly 24,000% on their original investments.

Was this little musical one of the best investments of all time?
