The letter of the day is "A," as in "Awwwww": Dave Matthews stopped by Sesame Street recently where he and Grover shared a song about feelings. The clip opens with a despondent Matthews sitting on a stoop plucking a banjo when a bummed-out Grover joins him in commisserating about their mutual feeling of a not-very-good feeling.
Without a word to describe that feeling they're feeling, Matthews offer the best solution: A song. In the adorable duet, Grover laments his unfulfilled wish for a rocket ship, while Matthews bemoans his inability to take to the sky with his superhero friend. But of course at the end of the song, all somberness goes out the window when Grover realizes the word that best describes his mood is "joyful" because he's got a good friend.
