I believe it was a Geodude in SoulSilver. I've gotten quite a few shinies throughout my life besides that though. Koffing in Soul Silver (the exact same game, too), Budew in Platinum, Lillipup in Black 2, Amoongus in Blaze Black 2 (ROM Hack), Audino in Blaze Black 2 (I forget if it was the same run), and most recently I got a shiny Wooper and Qwilfish in the same day after two eggs each!
