1x8 - The New Addams Family

Cousin Melancholia's fiancee ran out and left her, so she shows up at the Addamses house all despondent. They try to find her another suitor - the mailman who zooms off, Lurch wouldn't agree, Fester only dates criminals, and Thing fingers off. But the unwilling Ralph Harvey, trying to save his Law Firm's account with the Addamses, is coerced into dating and getting engaged to Melancholia.
