Getting an Eyeful (1938)
Buddy: It's preposterous. It's unheard of. Married! Married to a rubber-brained ninny with the intelligence of a sausage and the personality of a herring - a dead herring.
Henry Groper, Optician: Oh, there's something wrong with your eyes? Oh well, that's why you thought I wasn't who I was.
Nikolai Nikolaevich: Oh, you are who you are, aren't you?
Henry Groper, Optician: Certainly!
Nikolai Nikolaevich: Uh huh. I thought she was not who she was. Was she who she was not and you was who you are? Are you?
Henry Groper, Optician: What's the matter with you anyway?
Nikolai Nikolaevich: My near sight is getting too close to my far sight.
