Selma and Irving receive an invitation in the mail. Since it was many years since they were invited anywhere, they read it with glee, very excited that they were asked to attend a wedding.

All was fine until they reached the last line. Confused, Irving asks Selma, "Selma, vat does this "RSVP" mean?"

Selma was at a loss, as for the life of her, she simply couldn't remember.

Finally, she cries out: "Vait! I remember! I remember! RSVP!! It means "Remember, Send Vedding Present!"
