A Tornado, a 10-Hour Flight and a Darn Fine Ring

The Warner Bros. Ranch back lot, where the exterior of Meemaw's house was filmed, has been sold to another company for sweeping renovations and is scheduled for demolition. The scene of the house with "tornado damage" was shot during demolition and the house is now gone. EDIT: This is fortunate timing, as Sheldon goes to Germany for the summer and in La teoría del Big Bang (2007): The Pancake Batter Anomaly (2008), he tells Penny that he was alone in Germany due to his mom having to return home due to tornado damage because "the house had slipped off the cinder blocks again" due to it being an aluminum house. This episode seems to be retconning it to Meemaw's house being destroyed instead, particularly since both houses have always been depicted as stick-built houses, neither one being aluminum nor on cinder blocks. UPDATE: Oct, 2023: The Warner Bros. Ranch back lot has been leveled. All the historic television and movie locations have been torn down and hauled away. Even the pool has been emptied, torn up and filled in. A sad day for the entertainment industry.

The exterior shot of Sheldon's aircraft in flight is of a Boeing 787 Dreamliner in the Continental livery, a model not introduced until 2009 and never flown by Continental Airlines. This episode takes place in the 1990s. EDIT: The aircraft type appears to be a 777, a type introduced in the mid-1990s. Continental operated several Boeing 777s from 1998.
