Auld Lang Syne, or "That Weird Song Nobody Knows The Words To" referred to by Robin, is a traditional song in the episode "More of the Same." Robin gathers Starfire, Cyborg, Raven, and Beast Boy in the Titans Tower's bathroom to orchestrate the song. The four Titans sing timidly, not knowing what they are doing, and Robin eventually takes over singing it himself.
Starfire, Cyborg, Raven, and Beast Boy: Should auld acquaintance be forgot, Something something something...
Robin:(yelling) That's not how the song goes!
Cyborg:(talking normally) No one knows the words dude!
Robin:(talking normally) Well, I do. Now, sit back and listen to these bittersweet lyrics.
Mi mi mi.
Should auld acquaintance be forgot
And never thought upon?
The flames of love extinguished
And fully passed and gone.
Has thine sweet heart now grown so cold,
That loving breast of thine,
That thou canst never once reflect,
On Auld Lang Syne?
Raven:(talking normally) Wow... I liked our version better.
