What was Kareem Abdul Jabbar's embarrassing moment on Jeopardy?

Kareem Abdul-Jabbar appeared on October 15, 2009 for the 2009-2010 Million Dollar Celebrity Invitational quarterfinal game 2. In the Double Jeopardy round, he picked category "I Went To UCLA" for $400. The clue was "Tell your old man to drag this '70s UCLA & Trail Blazer center (& Lanier!) up and down the court for 48 minutes." KAJ replied, "Who is Kareem Abdul-Jabbar?" Alex replied, "No! (laughing) You're the one who delivered the line, but it was about Bill Walton... Embarrassing moments on Jeopardy!" KAJ looked totally confused.

For those who have no idea what this is referring to, in the 1980 film "Airplane" he said that quote to a few children. The Jeapardy question was asking who he was talking about (Bill Walton) when he thought they are talking about who said it. And it made perfect sense because Kareem went to UCLA.
