My Dialect is a Mess

There are times that I swing into a long vowel sing song CanadioFargoPacNoWesto drawl. It is of maddeningly untraceable origin. Well, more vague than untraceable. It happens when I drink a little and sometimes when I meet someone new. And apparently every now and then when I talk to my son's godfather on the phone. Either way, the whole looping softness slips away at some point and I start to sound like any other goofball who's lived in California for any period of time. Anyhoo and needless to say, when Tim Guffigan posted this, there was no slake of the mystery.
