Season 6, Episode 8: "The Mom And Pop Store"

I saw Mom and Pop this morning...

...but when I went by the store on my way home, the place was empty.

Everything is gone. Mom and Pop...vanished.

-So all my sneakers are gone? -I'm afraid so.

And that's just the tip of the iceberg.

I've been asking around. They didn't even have any kids.

Mom and Pop aren't even a mom and pop?

It was all an act, Jerry.
