The Addams Family s01e12 Morticia, The Matchmaker

Cousin Melancholia visits. Abandoned by her fiancé, she needs a man. Meanwhile, the firm of Ferguson-Riche & Fisher wants their Mr. Harvey to broker a deal with the Addamses since he's the only one among them who's dealt with them before (a fact which leaves Mr. Harvey repulsed at the thought and determined to resist further contact). When the Addamses learn he's a bachelor, they're not only eager to meet him but ready to set the wedding bells pealing and heartily welcome him into the family before he can say yes (or anything else).
