Malcolm gets a crush on a girl, Alison, but has problems because he thinks too much. He enlists the help of Reese who shows him how to shut his brain off, but it has bad consequences. Stevie is staying at the house because his parents are out of town and Lois enjoys his company because he is such a good kid. Hal wins $1000 from a lottery ticket and rents a steam roller. Otto gets tricked into buying cow sun block, and Francis must get the money back.
- First appearance of Alison.
- Stevie addressed Lois by her first name in this episode, as opposed to "Mrs. Wilkerson", because the show attempts to keep the last name of the family ambiguous.
- The song playing while Hal is at the liquor store while buying the lottery tickets is "Habiby Ya Nour El Ein" for the Egyptian super star "Amr Diab."
