Hans sitting at a chair while the shrink shows him a series of images.
Shrink: (showing a picture of a rectangle) What do you see here?
Hans: It's a bedroom window, and look at all the trannys having an orgy in there!
Shrink shows a picture of a circle
Hans: That's a porthole! Full of "semen" doing what they do best!
Shrink shows a picture of a triangle
Hans: That's a keyhole! And boy, howdy! It's really bad in there!
Shrink: I believe you have a dirty mind.
Hans: Me??!!? You're the one with all the filthy pictures!
