"Pain in the Ass" . . . Mulder and Scully walked towards the Eurisko Headquarters, and obviously curious, Scully questioned him about Jerry Lamana.

     "How come you two went your separate ways?"

     Smart ass as usual, Mulder replied "I'm a pain in the ass to work with."

     "Seriously," she responded.

     Before answering, Mulder turned to look at her, a hint of delight behind the sardonic rejoinder, "I'm not a pain in the ass?"
