I'm guessing it's a goof - the names and homages are too spot-on to be otherwise. And Ted Griffin (the s reenwriter of Ocean's Eleven) is named as a "creative consultant", which would be a nice cover if (as I suspect) he wrote it.

But one thing's for sure, it's one of the best goofs I've ever seen.

CORRECTION: Richard Easton (not Michael) played Mr. Carroll.

And the character names were a great touch - "Roger Thornberry", "Grace Thornberry", "Leonard" (after Martin Landau's character in North by Northwest, and "Mr. Carroll" (for Michael Easton's dead-ringer take on Leo G. Carroll). Priceless.
