Al lets Della call Ed "Stella".
A nut for a jar of tuna
Cain: A maniac
Do geese see God?
I maim nine men in Miami.
Ma has a ham.
Ma is as selfless as I am.
Marge lets Norah see Sharon's telegram.
Murder for a jar of red rum
Naomi, did I moan?
Ned, go gag Ogden.
Never odd or even
Niagara, O roar again!
Pull up if I pull up.
Was it a car or a cat I saw?

and my favorite...

Nurse! I spy gypsies! Run!
