1x10 - Early Edition

Gary has to stop a man from his old office from killing himself. Marcia visits him with the news that she's getting married. She won't reveal the identity of her soon-to-be husband, but Gary finds out it's Phil Pritchard, his old jerky boss. Gary is not happy about it and a series of accidents make it look like he's trying to purposely hurt Pritchard and get in the way of their wedding. When the paper brings the headline that Pritchard is going to be murdered, Gary refuses to help him, but Chuck convinces him to do so. He also must stop Sam (the office mailboy for the past 9 years) from killing Pritchard.
