Thanks for pointing this out--I think you must be right! The sight of those old books certainly does take me back.
Since both Julia and Mrs Johnson were on set that day, I really think it's a shame that they didn't do a shot of Grayson and Clarice together for one of the books. Maybe Ross could have rewritten the plot of Arsenic and Old Lace with GH and CB as, I don't know, Delia and Adelaide Collins, the genial spinsters who rack up an impressive line of lonely old bachelors in their sitting room down at "the Cottage." I can just see GH rhapsodizing about the rare vintage of her elderberry wine... *smirk*
I just love the snapshot of Julia "at the console" as the experiment starts to go wrong. Great stuff! My warped brain suggests a caption: "Was that a double cheeseburger, no pickle, no special sauce, WITH extra fries???"
