Plot / Description

This commercial begins with a closeup shot of a microphone hanging. The microphone is in a boxing ring in an empty stadium. We also see an empty outdoor wedding ceremony, an empty stage for a rock band, an empty baseball stadium, and an empty bar. 
 
We then see the text, "Great times wait for the designated driver", and a man walks in telling everyone that he's ready to go. This man is the designated driver for this group of guys, and once they leave, all those empty places become full of people. Everyone (else) can have fun because there is a responsible person in the group.

Voiceover

Good night tonight, boys. I'll be the designated driver.
