Sweetest Thing: what bono says at end.

I just want to say that I have watched the end of the "Sweetest Thing"
numerous times now (I taped it) and I am still not sure what he says. I don't
think it's "How's that?" or "I'm fine". It looks to me like "I'm _____". I'm
not sure what goes there though. Logically one would think it's "I'm sorry"
but screw logic. That's just my opinion. I'm no expert though.

ps-I still am confused. Do you pronounce Bono with a long o or short o? I
always did it long.
