The Nintendo Pii is a video game console.
How to play with itEdit
Turn it on. The Pii pees on you and then you go wash up, then pee on the Pii, then the Pii pees on you, and you pop in a disc, which the Pii turns into pee and you blast it with a complementary ray. This ray turns the pee into a disc, which will be different.
When you get the new disc, you do the whole thing again.
And again, forever.
