Kirk found this great video made by TheOhioCountryBoy on YouTube.
Very occasionally a hive will turn mean to the point where the bees become unmanageable (it happened to Amy and me earlier this year). This video shows an elegant method of re-queening such a hive from brood with calmer genetics. It's a step up from Beginner's Beekeeping and requires you to put up with the mean bees for several weeks, but it has the great benefit of eliminating the bad behavior without losing the hive.
