I love a good ambiguous error message as much as the next guy, and injecting some fun into those error messages always makes my day. We came across a strange error in our database connection code the other day, and the following (100% genuine, Microsoft generated) stacktrace was part of the error:
at System.Data.SqlClient.TdsParser.Deactivate(Boolean connectionIsDoomed)
Seems my connection became doomed, then went on a search for braaaaains!!
