“The sap runs every two years.”
Watch for Biden to give a rehearsed answer to the wrong question. There was an “I Love Lucy” episode where Lucy appears on a game show and she gets the wrong questions in advance, so she rehearses the wrong answers.
Biden could also deliver some rehearsed zingers, but he will flub the line.
He could also mumble the answer to himself before the question.
The moderator will have to improvise to run interference and spin Biden’s answers and Biden’s eruptions.
In that same category: the "Honeymooners" episode where Ralph Kramden prepared for days honing his skills on pop music's song titles, composers, etc, so he could "Name That Tune" in as few notes as possible on the TV game show.
Ed Norton helped him practice for the big event by playing the hundreds of songs on the piano; but in doing so, he began each number with a fanfare made up mostly from the tune of "Way Down Upon The Swanee River". Ralph got tired of that intro and kept blowing up at Norton for throwing that bit in every time he'd play a tune.
So when Ralph goes on the TV show, he rattled off the correct tunes, one after another until it came to some notes to "Swanee River", and he had no clue what the name of it was. Hummina-hummina-hummina. Hilarious!
