The main character Doug Heffernan (portrayed by Kevin James) is a Mets fan in the show and in real life.
The Mets have been mentioned mostly throughout the entire show at certain points. In the episode Doug Out the main cast go to a Mets game at Shea Stadium. Some of the friends of Doug are also Mets fans. Such as his cousin Danny (portrayed by Garry Valentine) who is also his cousin in real life and a Met fan like him as well.
Throughout the show Doug is seen wearing mostly a Mets shirt of different colors and variations along with hats and shirts of the Mets minor league teams. In the episode Name Dropper, Doug's wife Carries asks him the name of the man who sells kebabs outside Shea Stadium and his wife's name which Doug replies correctly. That clip can be seen here. Other mentions of the Mets can be seen here and here.
Another episode is Catching Hell where Doug, Deacon, Carrie and Spence go to a Mets game at Shea. Doug gets tormented by a young Mets fan who throws carrots at him. During the game a homerun is hit and Doug robs the kid from it as it makes him cry as he taunts him with it. He later gets booed from the crowd as they throw things at him.
In Arthur, Spooner Doug is in bed watching TV. As he turns off the TV he says "Good Night, New York Mets" after possibly watching a Mets game.
In Offensive Foul a Mets banner on a newsstand can be seen behind Doug as he tries to cross the street.
