The words to the song in this cartoon are a little hard to hear, so these are the lyrics:

What Fassbinder film is it?

The one-armed man comes into the flower shop and says,

"What flower expresses...Days go by?

And they just keep going by....endlessley...pulling you...into the future.

Days go by...endlessley...endlessly pulling you...into the future"

And the florist says,

~ ~ ~ ~

"White Lily."
