The Warner Bros. Ranch backlot, where the outside 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 "
The Big Bang Theory (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 backlot 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.
