Quick Claw Crawdaunt used Guillotine twice in a row in heartgold frontier. Nearly threw my ds.
I've never seen a non-ever game shiny, in the probably 800 hours I've played throughout all pokemon games, and I don't even use repels much. My friend who rarely plays pokemon found a shiny wingull within 5 hours of playing sapphire.
Not really that strange but I caught both Kyurem and Regirock on the second dusk ball in black 2. Also caught 2 metangs within 2-3 ultra balls. Usually take forever on those pokemon with low catch rates.
