A possible concise summary is:
The Slo Mo Guys, Gav and Dan, invite Rhett and Link to try sabering champagne bottles open with a blunt sword. They compare their results based on the cleanliness of the cut, the amount of champagne lost, and the sound of the pop. They also capture the action in slow motion and watch their reactions.
