Story Time: So my niece and nephew decided to come visit us in Washington and sit in our car as we visited Canada a few times to visit family. My nephew is at that stage where his plushie Piggy is his best friend.
I was playing with this kids, questioning them how the pig was going to get across the border without a passport. They both got pretty panicky when we told them that without a passport the pig would be taken into customs and not allowed into the country. So their uncle help make them a passport. It's got a bit of an identity crisis, if you can spot the oddities.
The border crossing agents were pretty humored by the passport and we got three different border crossing agents to sign the passport as we went into Canada and back into the USA
