Malcolm: You can go now. Thanks for the ride.
Lois: Where are the parents? Are there no parents here?
Malcolm: Mom, please don't...
Lois: Where are your parents? Who's chaperoning this?
Reese: Mom, we don't need a chaperone.
Lois: Okay, it's me. [claps] We got two lanes here. Let's use them! You, you, you, you and you, you'll use that lane. You five use this one.
Malcolm: Mom, please don't do this.
Lois: Are you kidding? You guys are bowling. [sighs] You could cut the hormones around here with a knife. I mean, what kind of parent would leave these kids alone with themselves?
