Reese, Malcolm and Dewey tell their parents they will be spending the night at Stevie's house, while Stevie tells his parents he will be staying at their house (Dewey goes because he overheard their plans to go to a carnival and threatened to tell Lois).
They all sneak off to the county fair together, but they arrive as the fair is closing and end up being locked in and chased by a security guard. Hal and Lois were going to spend the entire evening having sex until Stevie's parents showed up and they all discovered that their sons had lied.
