Quote from Hal in Jessica Stays Over
Hal: Malcolm, you wouldn't happen to know the life expectancy of a bee, would you? Malcolm: I don't know. Hal: Great. What's the point of hauling around that giant head of yours if you can't retain a few simple facts? Lois: Hal, he gets enough pressure from school without his family piling on. Malcolm: [to camera] Did Mom just defend me? Wow, this vulnerability crap is more effective than I thought.
