“Jeopardy!” interim host Mayim Bialik was explaining her dislike of musicals Tuesday on “The Late Late Show” when she recalled her falling-out with Neil Patrick Harris after he performed in “Rent” in the 1990s. Bialik and her boyfriend went to see Harris, then a friend, in the production. When the show got a standing ovation, an underwhelmed Bialik said she turned to her companion and said: “I don’t want to stand for this.”
