This song led into at least one Animaniacs episode and I'm pretty sure several others. It was also a call-on for classical music or when Germany/Switzerland/etc was the setting. It also also appeared in Disney's Fantasia. I love how bouncy it is in the beginning as well as the more thoughtful but still light section(s).
So, without further ado: Beethoven's 6th, 1st movement.
day 01 – your favorite song: "Shades of Gray" as performed by The Monkees.
day 02 – your least favorite song: "(She Was A) Hotel Detective" by TMBG.
day 03 - a song that makes you happy: Beethoven's 6th, 1st movement.
