 Television critics praised " Lisa the Vegetarian " for its humor . John Serba of the Grand Rapids Press named it his favorite episode , " because the tale of Lisa 's conversion to vegetarianism has more humorous scenes per square inch than any other episode . " The Ventura County Reporter 's Matthew Singer thought it was " overflowing with great individual scenes " , particularly Troy McClure 's Meat Council propaganda video , which he said " may be the funniest isolated segment in the history of the show . " MSNBC 's Patrick Enright , who listed the episode as his second favorite of the series , highlighted the " You don 't win friends with salad ! " song as " one of those archetypal Simpsons moments , one in which the writers hit a joke so long that it goes from funny to unfunny and back to funny again . "
