na na nu nu
That weird greeting from Mork, the alien on TV, who would say 'na na nu nu' like he was high on magic beans and did a weird hand thing like a star trek guy.
My brother said 'na na nu nu' to my mom and got grounded.
My teacher said 'na na nu nu' and made us do extra homework.
My dog barked 'na na nu nu' at the mailman.
