During Tucker's converstaion with Lois in the garden, the American flag patch on her right shoulder was backwards.
This is only the second time we hear Jamie speak on the show when he says 'Francis'. The first time was 'shut up' when Lois wouldn't stop talking.
This episode has three different segments that take place while the house is blacked out, all having a relation to one another. They all come back together after the power returns.
This episode has no "Camera Commentary".
Malcolm: These girls are from Amsterdam, they don't even have a word for virginity there.
This is untrue, the Dutch word for virgin is maagd.
When Vicki is pretending to be superficial and stupid in front of Malcolm, she says she had to take part in a discussion whether gloss or glitter is better. Malcolm whispers to her that he thought the issue was resolved with Fermat's Last Theorem, causing Vicki to laugh. Fermat's Last Theorem is a famous conjecture by a French mathematician in the 17th century that was only proven in 1995. This is one of the most famous theorems in mathematics.
The song playing in the background during Lois' dream sequence about her and Hal when they are old is a modified version of the Malcolm theme song.
Malcolm and Reese's high school looks different than it did in seasons 4-6.
Goof: Reese seemed to use a page of a Spider-Man comic book for toilet paper, but the magazine cover wasn't a Marvel publication.
In the scene where Dewey shows Hal his score in Mini-Golf, on the fridge there is a picture of Mojo Jojo holding an ancient dog head statue from Episode 103 - "Monkey See, Doggie Do."
Dewey's playing on a Gameboy, but just like in "Rollerskates" it still has no cartridge
It is revealed that the family's house was the scene of a murder. Lois knew about it, but Hal didn't until this episode.
This is the third and final time Lois gets arrested during the series.
Hal hates people with fake knives in their heads.
Hal doesn't believe in ghosts, but he does believe in "an energy, a life force, a soul that separates from the body..."
The exoskeleton that Stevie wears is based on actual medical studies that are ongoing. Many different universities and doctors are working on assisted movement exoskeletons with a wide range of medical applications. The US military branches actually have some in test phases, being used on soldiers who were crippled in the line of duty.
It is revealed that one of Stevie's problems is motor neuropathy. Motor neuropathy is a nerve disability in which the nerves either cease to fire or fire incorrectly, which results in either no mobility or poor movement control.
This marks the only episode we see Stevie (Craig Lamar Traylor) 'walk'.
When Hal asks Dewey where'd he get cigarrettes he said "Hal's shop vac", which he claimed had 20 cartons in there! I'm sure he meant 20 packs, because think of the space 20 cartons would take up!!
Jamie's first word is, "shut up, " but no one heard it.
