Clark steals a Viva Vegas Tour bus and drives to Shenandoah to get Ellen away from Wayne Newton. They then pull Rusty from his high roller suite and retrieve Audrey from her cage. With the Griswold family back together again but out of money, they decide to use their last $2.00 to try and win some back by playing a game of Keno. While Ellen chooses the numbers, Clark talks with the man seated next to them. Lonely Mr Ellis (Sid Caesar) wants nothing more than a family, so Clark invites him to be a part of the Griswold family for the night, and Ellis gratefully accepts. The Keno caller begins to call out the winning numbers, but the Griswolds get only one of the 10 numbers. However, Ellis gets them all, winning the game. Suddenly, Ellis keels over, dropping his Keno card on the floor. Rusty goes for help, but Ellis revives long enough to whisper 'Take the card' in Clark's ear before he passes out again. Just as the medics arrive to carry him away on a stretcher, Ellis winks at Clark. Clark retrieves the fallen Keno card and, with the windfall, decides the time is right for him and Ellen to repeat their vows. In the final scene, Clark gives Eddie $5,000, and Rusty points out the four cars a Dodge Viper, a Ford Aspire, a Ford Mustang, and a Hummer H1 that he won. Each of the Griswolds take a car, and they head back to Chicago.
