Malcolm in the Middle (2000) : 6x20

After Lois and Hal are reminded of the tight budget they must uphold, Hal discovers one of his boys has been dialing a 900 number. His attempt to explain the error to the hotline's billing department turns awry when he forgets to hang up the phone, incurring a whopping $800 charge. Meanwhile, Reese takes a job at a research clinic that pays him to pop experimental pills, and a reluctant Malcolm takes on a mortifying job at the Lucky Aide as a costumed Uncle Sam on stilts.
