Sr. Bertrille ends up in the doghouse when she takes care of the mutt owned by Felix the plumber (Gino Conforti). She does such a good job that the dog refuses to return to its master-and the heartbroken Felix refuses to repair the pipes in Carlos Ramirez' casino. Want to bet that Sr. Bertrille solves this problem by taking to the air again? "Man's Best Friend Isn't" was written by Milt Rosen; the episode first aired on February 13, 1970. ~ Hal Erickson, Rovi
