The problem with knowing the phone number for the pizza place off by heart

• Dad: Have you rang and ordered?
• Me: No, I always call. You call for once.
• Dad: I don't know the number.
• Me: And you can't just get the number?
• Dad: But you already know it.
• Me: But it's just as easy looking it up and ringing yourself for once.
• Dad: We just won't eat then.
