We used to have an old 78 with 'Bugs Bunny' singing -
now how did it go-

My teeth stick out in front
like bisuits in a fence
and as far as pictures go
mine's not worth two cents

but I'm glad to be the way I am
Who cares if I look funny
no matter what the others have
I'm glad that I'm Bugs Bunny

Thats all that I can recall at the moment, assuming there was more - the other side was Tweety pye and 'I taut I taw a puddy tat'.
