- Title: The Big Bang Theory – The Cohabitation Experimentation
- wiki: link
A burst pipe in Amy‘s (Mayim Bialik) apartment has domino effects for her boyfriend and roommates. Presented as a five-week experiment, Amy convinces Sheldon (Jim Parsons) to live with her in Penny‘s (Kaley Cuoco) apartment while allowing the newlyweds some much-needed alone time. The results are what you would expect – untempered glee from Leonard and Penny and new struggles for Sheldon and Amy (some of which provides amusing moments including Leonard’s words of advice for Amy). The episode also throws in a B-story involving the Walowitzes most notable for the pair calling and hanging up on Raj (Kunal Nayyar) repeatedly in the middle of the night.
