My first shiny (after that awesome red G in silver!) was actually Lugia in soul silver. At the time I was moaning to my partner about never having found a shiny so wasn't paying attention to the battle. When I looked I said "why the hell is it pink?! OH MY GOD IT'S SHINY!" Then immediately threw my master ball at it xD my partners fave pokemon is Lugia so he was pretty stoked. I called it Topaz and I love it!!!! I've only found 3 more shinies randomly since then, a foongus in black and skarmory + combee in Y.
