I did something really stupid in 2007 while I was playing Diamond (I had been playing somewhat less than a year at the time):
I was at that part of the game where you battle Mars and Jupiter in a double battle and your rival is battling with you. My team consisted of a level 40 or 50-ish Torterra (my starter), a level 30 or 40-something Staraptor, a Lucario that was in the 20's, 30's or 40's, a under level 20 Pachirisu and Buneary and something else if I remember correctly. I got destroyed by Mars and Jupiter for obvious reasons, so I got furious and trained Torterra for a few months until it was level 70-ish. I whooped their behinds. :P
I also stopped using Pachirisu and Buneary after that. I will not use them again even if one gives me $20.
