I used to spend all my free time hunting glitches and hidden things like this, before I discovered the Internet. I actually permanently destroyed the ability to save in about five cartridges as a result, but hey, totally worth it.

Hmm... I felt obligated to actually try them all, though I honestly never believed them. I think the most annoying one was the one where you had to buy a girl lemonade 255 times, and then she'd evolve Flareon or something. The details are fuzzy.

One I never really used was the one that said you had to input this huge complicated button code as you threw a pokeball and it was a guaranteed catch. The actual button code was a well-timed 'B'. I laughed whenever I saw it as 'Up down up left right A A start B' or something.

Then there was the infamous 'Beat the Elite Four however many times without healing at all and you'll get _____' or 'Beat the Elite Four with a team of Caterpies and you'll get ______'.

On a more amusing note, I once found a cheat that said you could 'catch Professor Oak'. I tried it, naturally, and nothing happened. However, on a different cartridge sometime later, I found a wild Professor Oak on the coast of Cinnibar, and caught him. Unfortunately, he took his revenge, it seems- Even opening the box with him in it froze and deleted that game.
