Old CatDog and the Sea - S3.E18

This is a salty old fisherman's tale about the Swordfish on CatDog's living-room wall. The teller of the tale is Cat, who's embellishing the story in order to impress TV star Tallulah. But Dog can't resist getting in on the act, and spins a wild yarn that Tallulah finds more interesting than Cat's. Cat, frustrated and outdone, finally reveals that the fish was actually purchased at a yard sale.
