Oak: But that's illegal!
You: Illegal, wait a minute....
you pounce upon Oak and begin trying to uncover his mask.
You: COME-- OFF-- THIS-- WIG--!!
Oak kicks you and you cry like a little girl.
Suddenly, there is a squawk, and you both dash headlong into a goose.
You capture only 789 feathers.
But you chose a pokemon anyway. You decided on a goose as one.
