Quote from Phoebe in The One After the Superbowl (Part 1)
Phoebe: Today, we're gonna start with some songs about barnyard animals. [playing guitar and singing] Oh, the cow in the meadow goes "moo", Oh, the cow in the meadow goes "moo", Then the farmer hits him on the head, And grinds him up And that's how we get hamburgers. Now chickens.
