POST 4-CONCEPT 4

In this episode, Sheldon believe he can prove knows all the ingredients of Pringles chips. A whole quarky discussion is taken place about Pringles and multiple shots are taken of the product in multiple peoples hand. I believe the product placement is effective because it is used in humorous ways by sheldon and the cast. The cast and writers are very good at making a small, ineffective topic become a primary source for a whole 30 minute show.
