5x14 - Malcolm in the Middle

Lois blows her top over a hidden 15 percent surcharge on the bill at her family's favorite pizza place and stages a boycott...but Hal and the boys are sneaking slices on the side. Malcolm meets Angela and becomes instantly smitten with her intellectual family...but starts to feel like a heel because he's asked another girl to the school dance and is forced to break it off with her--er--them. And Francis is reluctant to let Otto hire an assistant for him...but soon comes to like the idea.
