Gordon Gets the Giggles is the seventh episode of the twenty-third series.
Rebecca is getting into accidents in the yard: getting herself covered in honey after bumping into a truck full of honey jars, almost colliding with Thomas and bumping into trucks of fruits and vegetables which end up covering her. Thomas laughs at her accident, which Rebecca also sees the funny side to. Even Gordon can't help but laugh, which surprises Thomas and Rebecca, but he attempts to cover it up as he leaves.
While pulling the express, Gordon can't help but laugh constantly. He attempts to control himself, but just keeps laughing. Thomas sees him laughing, to which Gordon attempts to explain that he thinks he's got something wrong with his boiler. Thomas thinks so to, and advises Gordon to go to the Steamworks to get it fixed.
Gordon still keeps laughing and even rushes through a level crossing to get away from Rebecca. He becomes even more worried when he thinks Sir Topham Hatt will make him be a clown if he doesn't stop laughing. Once he gets to the Steamworks, Victor tells Gordon that he's fine and there's nothing wrong with him. The Fat Controller then assures Gordon that he won't be replaced and that it's good to have a laugh sometimes, which Gordon agrees.
