Continuity mistake: In the last scene when they are all on the fire escape, there is one part where the landing nearly collapses and Sylvester is seen nearly flying off the landing. The next immediate shot shows Sylvester fighting for the ladder. He apparently climbed up the landing and crawled over a bunch of people in a fraction of a second.

Starring: Spencer Tracy, Peter Falk, Mickey Rooney, Carl Reiner, Jim Backus, Buddy Hackett, Jonathan Winters, Sid Caesar, Milton Berle, Phil Silvers
Three cars and a moving van witness a man drive over a cliff in a car. When they pull over to see what happened, the man tells them about $350,000 he secretly buried "under a big W." They agree to not let the police know and all start racing towards the location of the money. They don't realise they are under police surveillance the whole time they are en route and do everything but kill one another in trying to get to the money first.
