Cloris Leachman returns in her Emmy-nominated role as the spiteful and irascible Grandma Ida. She's even nastier than usual (if that's possible) because of a tumble down the front steps that resulted in a broken collarbone, prompting her to sue her daughter and son-in-law for pain and suffering. And there's more momentous news on the home front: Lois is pregnant. So she pleads with Ida to reconsider her lawsuit: "We're already stretched to the limit financially as it is. Obviously, a new baby is going to make things even harder on us." "Yes, yes, of course," Ida concurs. "You should settle."

Once there, Lois immediately feuds with Dorene, the loud-mouthed mother who dominates the other parents; Reese plans to "kick Krelboyne butt" and is hoist by his own petard (okay, underpants) by Eraserhead's much bigger brother; Francis goes through an entire romantic relationship in the course of the single afternoon; and Hal grosses out the entire class by sneaking real meat into their vegetarian barbecue.

Perhaps the most original sitcom pilot in recent years, this first episode combines sharp writing with a hyperbolic camera style reminiscent of Parker Lewis Can't Lose. Malcolm introduces us to his world, dominated by omnipresent schoolyard bully Spath and made worse by his enforced friendship with Stevie, an asthmatic wheelchair genius. When a battery of tests reveals that Malcolm has an IQ of 165, he is moved into Stevie's special accelerated class, despite his protests that "around here being intelligent is exactly the same as being radioactive." On the bright side, Malcolm discovers a practical application for intelligence when he and Stevie spontaneously hit on a solution to Spath's persistent tyranny.
