Season 6, Episode 3: "The Pledge Drive"

-Hello. -Jerry, hello.

-Uncle Leo. -Listen, I don't wanna alarm you...

...but your nana is missing!

Nana's missing?

I came to pick her up for her doctor's appointment.

She wasn't here. I called the doctor. Nobody knows where she is.

She hasn't left the apartment in 25 years.

I've been thinking about her. I just cashed some of her checks.
