(Via No Quarters)
Because if you do, some smart fellow may put your sorry, no-good behind on the Internet so that you can face the public humiliation you richly deserve.
How NOT to steal a SideKick II is the tale of some NYC ner-do-wells who thought they could get away with keeping a $400 mobile phone device they found in a cab. After being nicely asked to return it, even after being offered a reward, they refused--then they decided to play tough. They found out that Evan Guttman was tougher (registration required, BugMeNot is your friend).
Good work, Mr. Guttman. All things considered, I doubt they've learned the lesson in civility you were trying to teach, but I expect they have learned another--watch out who you mess with.
