Well it's happened to all of us at some point in the years we're played these games. We've all had our close battles and the ones that are blowouts one way or another. However every so often we'll have a battle that makes us stop and go "Did that really happen?"
The battle that prompted me to post this actually happened a few days ago. I recently got a copy of Ruby and finally got around to playing it. While trying to train my on Route 101 I actually had my Mudkip miss with tackle FIVE straight turns (and no.....sand attack was not used at all in this battle). Mind you this is an attack with a 95% hit rate. Needless to say it didn't end well.
