Too Much Time Around Bagpipes

I mentioned to my wife that my employer was again raffling off a Glock 22.  (They do that a lot, since that's what the state issues to the employees who have confront stuff more dangerous than criminally bad software.)  But what she heard, as a result of too many years in the presence of bagpipes was, "We're doing a rap about Block 22."  A rap about life in prison?  Well, that makes some sense.
