On last week's episode of 'The Sopranos' ("Road Trip"?), Christopher Moltisante and his new bride Kelly went home-shopping and he fell in love with the first house they were shown.
"Now that's what I'm talking about," he said in awe as he gazed at the house. "Stately Wayne Manor!"
This was how Bruce Wayne's residence was described by the narrator of 'Batman' back in the mid-1960s. But I don't see a Zonk! in Christuphuh's use of the term.
The Wayne mansion was an architectural marvel, even if the general public didn't know about the Bat-pole which led to the Batcave below.
As such, the home shared by Bruce and his ward Dick Grayson more than likely appeared in several Toobworld-based architectural digests and magazines. And in the captions for the many pictures taken of the property at large, I would think "Stately Wayne Manor" would be a natural description of the property.
So it's possible that the phrase stuck in Chris' mind while his ex-fiancee, Adriana, forced him to look through those magazine in hopes of finding the type of home they should one day live in.
If she only knew......
