The times I've seen DB on TV he is very "dead pan" in his presentation, and he doesn't communicate sarcasm well. I didn't hear the episode but it could have been his attempt at sarcasm.
He’s great on TV! On the radio for 4 hours every morning (1620 The Zone), you know he has time to fill, especially when co-host Gary Sharp is absent. That’s when he sometimes gets into little teasers, etc,.. I know he’s just trying to create interest, that’s his job. I don’t mean to bag on him...
