Vārdi: Sesame Street. I'm Proud.

(upon arriving at his new job, working with the famous scientist, Dr. Igor)

I'm proud!
I'm proud!
Who wouldn't be
If he or she was me?

(a little later)

I'm proud!
I'm proud!
I'm tickled pink -
It's my instinct ...

I think ...?

(and upon solving experiment #1-CX - the maze!)

I'm proud!
I'm proud!
Who wouldn't be
If he or she was me?
Ta-da!
