Quote from Jill in Quibbling Siblings
Jill: And, see, this is kinda harder for Randy, because he's a middle child, just like I was. Brad: Mom, Mom, please. Not the wallaby story. [exits] Jill: We went to the zoo every year. [Tim enters] Robin got to see the monkeys. Tim: Oh, no, no! Jill: Katie got to see the zebras.
