I Do Not Choose to Run - S5-E16
Factual error: When Rob tells the name of the street he lives on in this episode "Bonnie Meadow Lane" that was not the same as the past episodes which was "Bonnie Meadow Road" in all the other episodes except for when Rob and Laura were buying the new house beside Jerry and Millie's house.
Factual error: The bad guys are supposedly auctioning off the stolen Mona Lisa. But they and their prospective buyers aren't very art savvy. The painting is more than twice the size of Da Vinci's actual masterpiece. (00:44:50)
