Fans of the band They Might be Giants probably would have gotten this right away, because it's part of a rather memorable series of songs called Fingertips. I made a video where you can listen to the Oracle say the line, then the song plays.
I happen to know that the person who suggested that saying for the Oracle is Arthur Wethersfield, and that Wizard101 isn't the first game that he worked on that he got the line into.

Gnu Gnu is Arthur Wethersfield's alter ego I guess. I think it's funny because the game was made for Game Boys that could only display four shades of green.
And that is what that blue thing is doing here.
