George and Lynne have a friend called Carol. Carol has only recently moved to the neighbourhood as George knows nothing about her. Either that or George has no interest in any of Lynne's friends. Lynne insinuates that Carol's nameless husband is gay. George tries some one-up-manship on Lynne's usually awful jokes by making a pun out of the word perfect and the word purr, which is the sound a cat makes when it is happy. It seems that the gay husband of Carol doesn't say anything because he doesn't want anyone to know he is gay, or he is living in denial. Either way, Carol is his beard and they have a nice life.
I wonder how many cats Carol actually has and if the sheer number of them has ever got out of hand.
