Favorite Accident?

[HTA!]

For example, finding a shiny in the grass, randomly catching a wild Poke with great stats etc.

I recently caught my first shiny EVER.
A shiny Psyduck, totally random, while I was EV training a Hypno.

Finding a shiny Machoke (i evolved it into a Machamp) while going to the Pok?mon League on my Leaf Green version. Normally it wouldn't be a big deal, but I got to trade it for a lvl 100 Shiny Milotic. :)

I found a Surskit in Pokemon Sapphire on my first time through. I didn't know there was a low chance of finding it unless there was a swarm, but I still caught it.

It evolved and became part of my Elite 4 Team.

I accidentally beat the Elite 4 with a horrible team.

I once caught a shiny Solrock before I was even aware of what a shiny was.

Of course, I get the stupidest shiny ever. It's red instead of orange. Lame. :|

I tried that once when I saw someone catch the Johto Elite 4's Pokemon.
Stupid hackers.

I hatched a shiny modest Charmander. Originally I was hatching a Pichu eggs, but a Charmander egg got mixed in.
