Well, it happened to me twice now.
The first time happened when I dropped my gameboy after finally beating the Elite Four for the first time and I had not saved since I *started* my way through Victory Road. I was at a loss for words and my friend ribbed me about the face I made.
The second time was when I ground out the levels to get two of my pokemon to level 100, starting from when I last trained them at level 36 each. When I stood up, as the gameboy was on my lap, and the cartridge came out, I was too tired to even try to deny it happened.
I never want to see another Hypno or Nidoking for as long as I play this game now, though....
