One at a time! One at a time!

[all speaking at once]
Lisa: Mom, can you sign this permission slip for my field trip? Mom, I hate those pimento things. They make me gag. ... Mom, I can't eat those things!
Bart: Mom, have you seen my lucky red cap? Mom where's my lucky red cap? Mom why aren't you listening to me? Mom, I'm talking to you, hello? Hello? I got a test today. I gotta wear my lucky red cap... Moooom, I need my cap!
Homer: Marge, I split my pants again. Oooh, can I have two sandwiches today? Make them bologna sandwiches too. Can I have two slices of bologna and cheese?

Marge: One at a time! One at a time!
