Sucks to be Me

I have two songs stuck in my head today. The first one goes:

We fish gnu a mare egrets moose, We fish gnu a mare egrets moose, We fish gnu a mare egrets moose,and a hippo gnu year

Think "We wish you a merry Christmas." It was a shoebox card years ago.

The next one starts:

We're whalers on the moon, we carry a harpoon

It's from Futurama - Are you a fungineer?

I have no idea why.
