Just a few honorable mentions:
- After watching the third Pokemon movie, I though Unown would be a really cool Pokemon with awesome moves. Yea.. Hidden Power...
- I got the Master Ball in Sapphire, though when battling Kyogre, I accidentally defeated him instead of trying to catch him.
- I've used over 10 Max Repels at once just to make sure they're working.
- I've randomly just rode my bike or ran through the sand for five minutes as I enjoyed seeing the trail or footprints I leave behind.
- I've forgot to save (especially after defeating a gym leader).
