How to evolve Pokémon without trading!

First of all,
I DON'T TAKE ANY RESPONSIBILITY FOR THIS.
Don't worry, I'm sure theres no risks to this.. If you do it right.

UPDATE: Since people are posting comments that they can't connect, well you need Wi-Fi for this, if you don't have Wi-Fi, it won't work.

Ok, thanks Furyan for telling me this.

I know that there's no music.. Blame Youtube.. According to them I wasn't allowed to use the song because I didn't had the right.. I mean COME ON! There are milions of videos with music and I don't see those video's dissappear.. ._.

-- What to do --
1. You place your Pokemon on the GTS system, and ask for a idiot Pokemon like an Abomasnow lv 100 like I did.

2. You have to do at least one trade on GTS for this to work. Just look for Bidoof's or Geodude's whatever.

3. When you made your trade, go to your Pokemon that you've offered. Take it back and it will evolve!
