Leonard figures out what Sheldon is up to and confronts him: “You’re using
chocolates as positive reinforcement for what you consider correct behavior!”
Sheldon confirms that Leonard is right and offers him a chocolate.
Leonard refuses the chocolate and tells Sheldon that he should not train his
girlfriend as if she is a lab rat. Sheldon tells Leonard that there is no pleasing
him. Since Sheldon’s previous attempts at being nice had failed, he simply
decided “to employ operant conditioning techniques, building on the work of
Thorndike and B. F. Skinner.” Sheldon then boldly claims, “By this time next
week, I believe I can have her jumping out of a pool, balancing a beach ball on
her nose.” When Leonard forbids Sheldon from the further use of chocolate
to shape Penny’s behavior, Sheldon squirts him with water and scolds him:
“Bad Leonard.”
