Drew's Uncle Cecil leaves $10,000 inheritance to Drew on the condition that Drew gets married within 72 hours. He and Kate desperately try to pull a wedding together to cash in.
As overall stories go, this isn't that great. A lot of jokes fall flat, and this is the beginning of the end for Drew and Kate's relationship (a turn of events that I did not particularly enjoy).
The saving grace here is the antics of Lewis and Oswald, who steal the show once again. In fact, Lewis' acting with the Ark of the Covenant is one of my all-time favorite Drew Carey Show moments!
