During the scene where Lois is eating the dinner for two alone, she gets up to switch to Hal's spot to eat his steak. If you look very closely, you can clearly see that her steak is still left on her plate.
When Hal is pushing the sandwich along the table, it then clicks to him doing the same on the ground with it still on the plate. It would almost certainly have overturned in the drop.
Malcolm's Family's address is revealed: 12334 Maple Rd.
Goof: In the teaser when Lois comes out and says, "Wow, that was fast..." you can see Hal's legs sticking out and lying on his back as if he was working under the car. Then they switch to Hal trying to eat his sandwich under the car, and he is parallel with it, and on his stomach.
Reese: I'm already committed to this party.
Malcolm: Reese, you've seen enough teenage movies to know how badly this can turn out.
Reese: I haven't just seen them, I studied them and I have found the fatal flaw. In every single movie the party was on Saturday night. Mine's on Friday.
Malcolm: Reese, haven't you ever heard of Stockholm Syndrome? You're starting to identify with your captors.
Reese: What captors? These guys saved my life, man.
Malcolm: Because they decided not to kill you!
Reese: Same thing.
Dewey: We can't just leave him here.
Francis: Dewey, there's a principle I learned at military school. The needs of the many outweigh the needs of the guy who can't run fast.
Dewey: Didn't you ever play "Fort" when you were a kid?
Craig: Of course I played. I had friends, plenty of friends. And you're short.
Reese: Have fun at school without me, losers!
Malcom: Reese, think about it. It takes 26 hours to get to Canada, and 26 hours to get back. Your bag is filled with food and nobody called Grandma!
Reese: Wait, you mean I'm spending the entire weekend on this bus?
(Malcolm, Craig, & Dewey wave goodbye as bus starts moving)
Hal: Remember the plan?
Craig: As soon as you leave, put Reese on the bus to see his grandma in Canada, after school I take Malcolm to Stevie's, and Dewey stays with me! (hands on Dewey's shoulders) Guess you're the lucky winner!
Dewey: (nervous chuckle) Why are you splitting us up?
Hal: Because this was the only way the judge would let us leave town!
Cold Open: Lois brings out a sandwich to Hal, who is working on the car. When he goes to eat it he realizes his hands are filthy. He tries to eat it with just his mouth but the plate keeps moving. Lois comes out with a drink and sees Hal is back under the car and thinks he is done, but he is just trying to eat the sandwich.
