It don't matter who's in late night, Johnny's still the King.

Just listen to the audience go ballistic when Johnny sat behind Dave's desk at the 3:05 mark. If only he had done 2 minutes of improv (and you know he really thought about it) it would have been golden. But, Johnny is wiser than us all and knew to always leave 'em wanting more. Anticipation is more powerful than gratification. But to be honest he could have done the entire show impromptu and we'd still want more.

This is only one part of a memorial to Johnny. I recommend watching the whole show. Dave and Johnny had a special connection. One slight problem, the segment with Doc Severinsen is missing due to copyright issues.
