This week’s guest on “Wait, Wait, Don’t Tell Me!” is James Lipton, the host of “Inside The Actor’s Studio” who was parodied so frequently by Will Ferrell on “Saturday Night Live.”

The interview included two interesting facts about Lipton, who has a new autobiography out:

• His wife was the model for the sultry “Miss Scarlett” in the artwork for one of the most popular releases of the board game “Clue.” (I’d heard this one just recently, somewhere else where Lipton was promoting the book.)
• He is, seriously, one of the world’s leading experts on collective nouns (like “a pride of lions” or “a murder of crows”), and has written a book on the subject, “An Exultation of Larks.”
