I have taken over maintenance of other people's code in the past, and its generally a mixed-bag. Sometimes you inherit a plate of spaghetti, sometimes you luck-out and actually get a well architected and implemented codebase. The real payoff when inheriting maintenance though, is to read the fantastic comments left behind, such as this gem I unearthed today:

// if it's a number we should sort it descending because it is probably a date
// bad? no, this is AWESOME!!!! Regular expressions are for assholes.
