I haven't had the chance to experience that many wtf moments; I kind of rushed through the game. So my biggest one was probably beating the elite four, I'd just barely managed to beat the last gym, then I went and caught lugia (took 3 dusk balls, I was chuffed ;D) then I noticed I didn't have anything else to do except go face the elite four, so I was like awww man, this is gonna take alooot of training. I never finished gold on the gameboy though, so I didn't know what the johto elite four were like, so I decided to just give it a go out of curiosity. My best pokemon was my new lugia, level 45, all the others either level 41 or lower. Then I ended up storming though all four of them and then just beating Lance with eventually nothing left but lugia, twas a truly memorable moment :)
