I'm just gonna say my entire shiny story.
I got my first shiny after beating the black tower in Black 2, and a couple of months later i was going to show my cousin the trucks up by Floccesy Ranch, and on my way I encountered a shiny Sewaddle. In Pokemon Y, I have hatched a shiny Charmander after 39/40 eggs, and I'm currently Masuda Methoding for a shiny Beldum.
