Hey, folks, this is generation four, no talks about Ruby/Sapphire, FireRed/LeafGreen, or Gold/Silver here.
Ha ha, just about a week ago, actually. I was just training in Mount Silver and I ran into a shiny Rapidash. Since my brothers were in the room, I announced "SQUEE A SHINY" and they told me to catch it--which I was going to anyway.
Persistent bugger it was, I had to poison it, and it nearly KO'd itself out before I finally caught it. I was going to name it Celestia until I saw it was a male.
Funny how you don't pay attention to the gender when you run into something like that.
