Home Improvement (1991) - 8 mistakes in series 4

Visible crew/equipment: As Jill is describing how, when she stops at an intersection, the "car guys" revv their engines, a crew member can be seen reflected in the window behind her, moving across the stage from left to right.

Continuity: The conversation Tim and the others have at the hardware store becomes a lot different when Jill sees the (supposedly) same conversation on videotape. First of all, Tim's remark the "Jill's speech was so boring" has become "Jill's speech was so DULL". Secondly, Eddie's entire tale on how his wife wanted to change the fabric in the sun room is missing from the tape. And third, when Tim is talking about Jill's psychology studies, the expression "these terms" has become "these USELESS terms".

Continuity: At the beginning of episode 4.10, "Ye Olde Shoppe Teacher", Tim's lopsided toolbox that he made turns 180 degrees as Jill pushes it away. As Jill and Tim are talking, it turns back. Then it turns 180 degrees again just before Tim briefly leaves the room.

Revealing: In this episode, every time Wilson places a log on the block before splitting it, you can see a dark line on top of the log, showing where they were pre-cut.

Other: If Jill moved the hotrod back in the garage after it was filled with snow, why isn't there a clean spot where she sat in it to drive it.

Visible crew/equipment: At the end of the episode "The Route of All Evil", Brad and Tim are having a conversation at the dinner table and a camera crew member is reflected in the kitchen window.

Continuity: When Tim goes outside to talk to Wilson, the distinct three-looped straw he used is still standing in his antacid bottle. When he comes back inside, the bottle is on the table where it was, but the straw has disappeared.

Continuity: In the opening segment, as Heidi hands Tim his hot-air gun, he takes it with both hands, then lets go with his left so he's only holding the gun in his right hand. The angle changes, and Tim is once again holding the gun with both hands, before he once again removes his left hand.
