a conversation between 18-month-olds

Zak: Hey, do you know what today is?
Wyn: Thursday?
Zak: No. Well, yes. But no...
Wyn: Ummm, oh, I know! I read about this somewhere. It's the first day of the rest of our lives.
Zak: (Sighs) It's our 18-month birthday, smarty pants.
Wyn: Zowee.
Zak: And you know what that means?
Wyn: That Mom, Dad and a few fortunate others have now changed three years' worth of diapers between us?
Zak: Exactly.
Wyn: Double zowee!
