This document discusses various defense mechanisms employed by the character Barney Stinson from the TV show How I Met Your Mother. It analyzes situations where Barney presents himself as disgusted by Ted's behavior, avoids potential disappointment of rejection, reacts to learning his dad was not who he thought, denies Robin and Ted's relationship, refuses to admit his mother is lying, justifies a pre-nup, and accuses Ted of having feelings for Robin rather than deal with his own feelings. In each case, the document asks which defense mechanism Barney is displaying.
