Three men are drinking beer in a bar. The film suddenly goes into rewind. The men undo their beer sips, put their beers down and walk out of the bar (backwards). They walk backwards through a field next to a river and into an ice age. As they walk backwards their hair grows and they become prehistoric man frozen in a glacier. As time reverses they melt and are monkeys swinging backwards in trees, fish splashing backwards through the surf and dinosaurs running backwards as the meteor that caused their extinction flies back up in the sky. Finally they are lizards on the shore of a river. Three glasses of Guinness are shown under the words "Good things come to those who wait."
