Night Night, Little Marvin (from How I Met Your Mother) - Jason Segel/Alyson Hannigan

Night night little Marvin

Stars twinkle for you

The dream land trains are chuggin'

All your dreams will come true

And the horsie says Good Night

And the birdie says Goodnight

And the elephant says Goodnight

And the skeleton rib cage says Goodnight

And the robot says Goodnight

And the whole world says Goodnight
