Driving home I saw a billboard that said "You bet your Daisy Dukes." Immediately I thought "Oh, it must be rhyming slang." I spent the time waiting at the red light trying to guess what Daisy Dukes rhymes with that would make sense in a beverage ad. I was coming up blank.
As the light turned green, I turned to give it a second look and discovered that it actually said "Bust out your Daisy Dukes." Oh. Short shorts. Summer. Refreshing drinks. Got it. I shook my head and chastized myself for having read something entirely wrong.
It was several blocks before the more relevant thing dawned on me. This is California. We don't HAVE rhyming slang.
