So your sports talk dude's perpetrated a bit. But do they know how to CRAFT a bit. The pay off of the punch line is crucial-just like waiting on the punch line to a joke. If it disappoints, you might not want to listen to that jokester again. N/A for most "imaging friendly" promos because there's no time for set up. And without it, the punchline means nothing. But if you craft that bit as your promo, listeners are more likely to appreciate being drawn in when the punch line's finally delivered.
