I saw it here in Metro Detroit too. I have a feeling that someone pushed the wrong button and played the hispanic version of the spot, because later in the broadcast they had the same ad but it was in english. When I was doing spots, we'd always do a hispanic versions of the big projects, to air on Hispanic television.
As I recall, there was a gradual change in the Spanish/English mix. At the beginning, it was all in Spanish; after a few ads, it was some Spanish and some English; and at the end, it was all English. I think there was something subliminal going on, but I couldn't place a finger on it. Anyhow, it was odd.
