When it debuted: 1989
Segment lowlight: The self-indulgent finale.
Arsenio Hall was better at generating excitement than laughter. You've never seen a man drag out an entrance as long as he could. With an average running time of two minutes, some older audience members likely collapsed from fatigue after all of that jubilant clapping during his introduction.
The button on his intro, after far too much saxophone soloing, was a reference to his super fans, "The Dog Pound." The camera would focus on a section of the audience with a lower third making some joke beginning with "People Who...," such as "People Who Say 'No' to Drugs and 'Yes' to Free T-shirts" or "People Who are in the Witness Protection Plan." Or, if you're like us, "People Who Rolled Their Eyes Every Time This Bit Was Used."
