Mommy was picking Zach up from School on day when a little girl came up to her.
Little Girl: Zach's Mommy, can Zach come over to my house this weekend?
Mommy: Well he can't this weekend but some day he can.
Little Girl: You will have to know how to get to my house.
Zach: Don't worry we have a GPS, it knows how to get there.
