(2)

Sheldon: There’s just no pleasing you, is there, Leonard? You weren’t happy with my previous approach to dealing with her, so I decided to employ operant conditioning techniques, building on the work of Thorndike and B.F. Skinner. By this time next week, I believe I can have her jumping out of a pool, balancing a beach ball on her nose.

Leonard: No, this has to stop now.

Sheldon: I’m not suggesting we really make her jump out of a pool. I thought the “bazinga” was implied.
