Continuity: In the beginning of the episode, when Karen takes a Diet Coke from the refrigerator, she starts pouring it into a glass, and fills the glass halfway up. Cut to Jill for a second, then back to Karen, who is still pouring, but the glass is now only about a quarter full.

Continuity: After Tim smashes Al's display cabinet, it cuts to Tim, then back to the workbench and the wrecked cabinet. The pieces of china and the pieces of wood on the bench differ in the two shots. In the first shot, there are two whole teacups, one whole plate and a bit of a shelf on the bench (the shelf is on the right side of the screen), in the second shot we see a broken tea cup, one broken and one whole plate, and the piece of shelf has disappeared.

Revealing: Towards the end of episode 2.18, "Bye, Bye Birdie", Tim drops to the ground in the back yard while trying to avoid the helicopter. When Tim gets up, you can see the grass (carpet) move and wrinkle up.

Revealing: When Tim is falling, crawling and rolling on the snow-covered ground in the final scene, none of the snow clings to him or his clothing. He does not even get damp, even when he is lying on his back in the same spot for several seconds.

Continuity: When Jill is standing up to the other woman at Mark's karate class, she asks her "Will you stop calling my son 'Stick Boy'?" As the other woman replies "Then feed him something", her hands are on her hips, but when the angle changes, she has her right hand on her chest, with no time to move her hands between shots.

Visible crew/equipment: At the very end of episode 2.25, "The Great Race", the top of the set as well as the studio lights are visible.
