Often the Psych writers pick up or continue jokes made in previous episodes. These are most typically lines stated by Shawn such as "Gus, don't be [this little crevice in my arm]" or "...I've heard it both ways". the most long-running of these is Shawn's habit of giving Gus (or someone else) a phony name (i.e. ...and this is my partner Gus T.T. Showbiz).
