Lyrics
Don't Worry, Be Mr. Happy: Well, Walking on Little Miss Sunshine, any last requests?

Walking on Little Miss Sunshine: Well, there is one, but...Nah.

Don't Worry, Be Mr. Happy: No, go on.

Walking on Little Miss Sunshine: Well, you have such a beautiful voice.

Don't Worry, Be Mr. Happy: Guilty as charged.

Walking on Little Miss Sunshine: ''Uh-huh. I was wondering if you sing the entire score of the ''H.M.S. Pinafore.

Don't Worry, Be Mr. Happy: ''Very well, Walking on Little Miss Sunshine. I shall send you to Heaven before I send you to Hell!''

We Sail the Ocean Blue

And a two and a three and We Sail the Ocean Blue, And our saucy ship's a beauty. We're sober men and true, And attentive to our duty.

I'm Called Little Buttercup

I'm called Little Buttercup, poor Little Buttercup, Though I could never tell why.

I am the Captain of the Pinafore

What, never? No, never! What, never?

Don't Worry, Be Mr. Happy and Walking on Little Miss Sunshine : Hardly ever! He's hardly ever sick at sea!

He is an Englishman

Don't Worry, Be Mr. Happy: For he himself has said it, And it's clearly to his credit, That he is an Englishman! He remains an Englishman!
