Quote from : The Naked Gun: From the Files of Police Squad! Movie

Frank: [sings] Oh say can you see / By the dawn's early light / What so proudly we hail / In the twilight's last gleaming? / Whose bright stripes and broad stars / In the perilous night / For the ramparts we watched / uh, da-da-da-da-da-daaaa. / And the rocket's red glare / Lots of bombs in the air / Gave proof to the night / That we still had our flag. / Oh say does that flag banner wave / Over a-a-all that's free / And the home of the land / And the land of the - FREE!
